SEISMIC DESIGN STUDY OF HIGH SLOPE AT MAO STATION IN CHENGDU——LANZHOU RAILWAY

In traditional seismic design of slope,the most commonly used method is the pseudo-static method.Because of its limitations,a new method of seismic design of the slope is proposed based on the strength reduction dynamic analysis.The proposed method takes into account the interaction between the supporting structure and rock soil under earthquake.It can satisfy the design requirements of earthquake and static stability of slope.The internal forces of supporting structure are obtained by the method.So,it ensures the safety and economics of engineering design.The seismic design of high slope of Mao railway station demonstrates the feasibility of the proposed method in practice,which provides a new idea for the seismic design of retaining the slope.
