Seismic Performance Analysis Of High Fill Embankment

Dynamic responses of slopes is one of the marginal problem in rock mechanics and still presents a major challenge to designers .On the other hand, landslide hazard induced by strong earthquakes are very heavy in our country. With the economic development rapidly , the expressway construction of our country changes gradually from eastern area to western , and high cuttings or high fill embankments are already unavoidable. Viewing from the investment, using soil and stone material to fill embankment are both economic and convenient, and it becomes to a trend which use soil and stone material to fill embankment in the mountainous area. Once the slopes are destroyed, it will be able to create serious project accident and bring huge economic loss even life security. Therefore, studying on the seismic performance of high fill embankment has vital academic and practical meaning.In this paper, with studying of many related research work publication, the recent development of high fill embankment is summed up systematically. And the development, application and character of analysis methods of slope stability, including static and dynamic stability analysis method ,are manifested . Meantime ways to express the seismic stability of a slope are discussed in this paper.To find the change rule of the acceleration, speed, displacement and dynamic stability with different slope height, gradient and filling soil, we will use the finite element method combination with Chinese seismic design code to analysis the dynamic response and dynamic stability of high fill embankment.The conclusions of this article will enrich the fruit of dynamic response analysis of slopes, and also can provide references for the design of high fill embankment.
