摘要:
In order to study the mechanical properties of anti-floating anchor rod in medium-strong weathered red sandstone and its application in engineering examples, this paper takes the virtual university town project of Hengyang High-tech Zone of Hunan Province as the engineering background. This paper had done destructive test of anti-floating anchor rod. The effects of different parameters on the adhesion of anti-floating anchor rod were studied by test and from three aspects: drilling depth of anti-floating anchor rod,highly and intermediary weathered sandstone. At the same time, the adhesion of anti-floating anchor rod in the same type of rock but with different drilling depths is compared and analyzed. The results show that under the condition of the same drilling depth, the adhesion of anti-floating anchor rod of different lithology is different, and under the condition of the same type of rock formation, the adhesion of anti-floating anchor rod of different drilling depth is not the same. The recommended bearing capacity characteristic value of the weathering layer is 1500 KPA, which can be used as the foundation bearing layer of the proposed building.
摘要:
The paper mainly studies buckling performance about corrugated steel web composite box girder of corrugated steel web under the action of a shear. Compare the two results of the corrugated steel web that calculating critical buckling stress through Abaqus finite element software calculating and theory formula. Obtain buckling strength of the model by giving the model initial defects under the elastic condition merely. In this paper, research trend of the buckling strength of corrugated steel web plate through changing the thickness of corrugated steel web, Angle, length of straight and wave height and the size of the corrugated steel web in practical engineering designing provide a certain references.
