| Abstract: | In view of the special geological conditions and complex structure of mountain highway,it is easy to cause the problem of highway landslide.a mountain expressway is used as an example to analyze the stability of highway landslides in natural state(deadweight condition)and saturation state(heavy rain state of deadweight state)by using the transfer coefficient method and FLAC 3D method,and a landslide control scheme is proposed.According to the results of the study,the stability coefficient of the landslide in the natural state is similar FLAC 3D the transfer coefficient method and the numerical simulation method.in an unstable state.In view of the instability of saturated state,two prevention schemes of slope cutting method and anti-slide pile method are proposed.The simulation results show that the slope cutting method is economical and effective,but it is easy to cause the superior landslide and cause the secondary disaster. |
