摘要：
This paper introduces the modal parameter identification method of a reinforced concrete block foundation under ambient excitation. On this basis, the dynamic characteristics of a stone cutting machine foundation are obtained by modal test under different operating conditions, and test results reveal that the main cause of abnormal vibration lies in lower dynamic stiffness of the whole structure. With the comparison of dynamic response between pre-reinforcement and post-reinforcement, reinforcement effects of high pressure grouting technique and pre-stressed bolt applied to restrain foundation vibration are verified effectively.
摘要：
According to the improved 3 scales (0, 1, 2) Analytic Hierarchy Process (E-AHP) and Extenics theory, an evaluation model is built to evaluate the slope stability. The model takes into account nine indexes that affect the slope stability. The classical matter element and extensional matter elemen are established by collectting actural data. And combined with the specific example, this model accurately calculated the stability state of the slope. The results shown that it not only can take advantage of Extenics Matter-Element theory and the correlation function to study the relationship between index and slope stability, but also can avoid the shortcomings of the traditional AHP judgment matrix inconsistent. It is a new model to evaluate the slope stability.

摘要：
Fe-immobilized bentonite, prepared with bentonite and FeCl3 was used for the adsorption of uranium(VI) in this study, solution pH, ion strength, contact time and temperature were investigated, structural characterization of Fe-immobilized bentonite was assayed by X-ray Diffraction and Fourier Transform Infrared Spectroscopy. Results indicated that the adsorption capacity were strongly affected by the solution pH and ion strength, the adsorption efficiency was 91.8% when pH value was 6 and ion strength was 0.01 mol•L-1, higher or lower pH did not favor the U(VI) adsorption. The adsorption mechanism was discussed by the views of reactive kinetics and thermodynamics along with Scanning Electron Microscope. The adsorption kinetics process was fitted well with the second-order kinetic equation, when the initial U(VI) concentration was less than 38.08mg/L, Langmuir equations could describe the adsorption isotherm of U(VI) well with the maximum adsorption capacity of 169.5mg/g at 303K
摘要：
This paper carries out dynamic tests of self-compacting prestressed concrete beams, 10 simply-supported and 5 free, then simulates modal analyses. It shows that, via comprehensive analyses of the first four natural frequencies and modes, the simple support can not achieve the ideal confinement effect for dynamic tests. Especially the tested high frequencies and modes are obviously different from corresponding theoretical values, instead the same as elastic-supported beams. The support plays the role of elastic one. The conclusions will provide meaningful references to further researches on prestressed concrete beams such as improving the accuracy of tests, dynamic analyses and theoretical frequency calculation.
摘要：
Considering the water-weakening properties of completely weathered granite, a lot of tests were done to study its water stability, and the regularity between water-related stability coefficient, a notion which is introduced, and compactness, the content of cement, the water content and cu ring time were discussed. Besides, the rule and mechanism of strength in the dry -wet cycles were researched by simulating the condition of underground water and rain waster. The result shows that the content of cement and curing time conform to hyperbolic curve, the compactness conforms to exponential curve, and the water content conforms to multinomial curve. As long as the strength of improved cement-soil arrived at some degree, the corresponding water-related stability goes unchanging as the microcrack growing under water-soil interaction. So it can provide the most economical way to improve the water stability for engineering by controlling the compactness.. the content of cement, the water content and curing time.

摘要：
This paper firstly presents the operation principle of individually ventilated cages (IVC) system. Measurements on micro-environment of IVC system in laboratory animal room at University of South China are conducted to attain the internal environment parameters (Temperature, humidity, air velocity, air cleanliness and noise). Research results show that internal micro-environment parameters basically meet national standards about the barrier environment, but internal air distribution is uneven. In IVC system, air velocities in the edge side are higher than in the middle side, and the maximum air velocity is about 10% larger than the minimum value. Temperature in internal micro-environment depends on indoor temperatures which IVC system located in, and there has a close correlation between air velocity and temperatures. Internal environment evaluation could provide the first-hand research materials for guiding the breeding and management of laboratory animal.
摘要：
Based on the one-dimensional wave theory, nondestructive testing with stress wave reflection method bolts is a kind of quick and effective detection method; the method was used to estimates the anchorage quality according to some parameters such as waveform, phase, amplitude, frequency as well as arrival time of both the incident wave and the reflected wave; stress wave velocity is the basic parameter for quality assessment, the velocity is depended on signal identification of the integrity bolts, especially the reflected ones from the bottom. This paper, through the transient dynamic response experiment of anchor in different anchor medium, analyzes the dynamic measurement signal waveform characteristics. The results show that, fixed end reflection signal is very strong , but bottom end reflection signal is very weak, even it is difficult to identify; the compactness of surrounding rock and anchorage medium have certain effect in dynamic measuring signal waveform characteristics, if surrounding rock and anchorage medium is uniform and dense, the wave type of anchor dynamic measuring signal is regular and steady, instead, signal clutter and irregular; model size and boundary conditions also have certain effect on the change characteristics of the signal, so this effect should be considered in laboratory experiment.

摘要：
There are two conventional techniques i.e. the approach based on structural testing and non-damaged detecting method, of which the former is partial to structural integrity analysis while the latter focuses on partial detection. The damage identification approach is discussed from the perspective of detection medium in the paper. And non-destructive testing in civil engineering (NDT-CE), of which the research status and existing issues are presented, can be attributed into three categories as following: one is based on the stress wave theory, such as impact-echo method, acoustic emission technique and ultrasonic pulse method; one employs the mechanism of electromagnetic wave propagation on behalf of GPR; one uses radiography as the medium, for instance, infrared imaging and computerized tomography. It is emphasized that ground penetrating radar (GPR) has been applied in practice and studied more and more, and moreover, the prospects in the field are provided.
摘要：
Using the numerical simulation method, this thesis studies the radon concentration distribution in downwind area of the flat ground uranium tailings impoundment with and without vegetation on the beach face under the wind speed of 0.5, 1.0, 2.0 and 4.0m/s. The numerical results show that the radon concentration decreases gradually with the increasing wind speed and distance from uranium tailings impoundment. As the wind speed is 0.5m/s, the radon concentration is higher in downwind area of uranium tailings impoundment, and accumulation range is larger and local pollution also becomes more serious. However, radon concentration and accumulation range falls rapidly with wind speed increased to 4.0m/s. At the same wind speed, radon concentration under the condition of beach face with vegetation is higher than the one without vegetation within 600m range of uranium tailings impoundment along the downwind direction, but radon concentration is lower under the condition of beach face with vegetation out of 600m range. It illustrates that vegetation can inhibit radon diffusion to some extent.
