In order to study the stability of dulanshan red bed landslide in group 2,Zongguan village,Xinglongchang Town,Luxi County,Geo-Studio software is used to analyze its safety factor and internal stress-strain.The analysis results are as follows:using Sigma/W module,it is found that there is horizontal stress concentration in the middle and lower part of the slope toe and slope top,the distribution of horizontal strain and horizontal displacement is large at both ends and small in the middle,and the volumetric strain is large at the upper edge of the slope and small at the lower edge;By importing ...
