Infinite Element Simulation On Dynamic Responses Of Slopes Under Earthquake Load

Our country is a nation that has many mountains and earthquakes, landslide disaster caused by strong earthquakes are very heavy. Therefore studying on the dynamic responses of slopes is very important in theories as well as in practices.In this paper, with studying of many related research work publication, the recent development of slope problem is summed up systematically. And the development, application and character of analysis methods of slope stability are manifested.Making use of finite element method, adopting infinite element boundary condition, dynamic responses of high slope are further studied. With numerical simulation of different acceleration parameters, slope height and gradient, variation regularity of the largest displacement, the largest velocity and the largest acceleration is found out. The gradient is less influence than slope height to acceleration, velocity and displacement, but has obvious influence to largest shearing stress and largest principal tensile stress.The conclusions of this article will enrich the fruit of dynamic responses of slopes, and also can give some references for practical earthquake designing of slopes.
