Study on seismic behavior of new self-embedded retaining walls

Abstract

This paper aims to explore the seismic mechanism of new self-embedded retaining walls through analyzing its embedded structures and numerical simulations, thus providing guidance for engineering practice and further development of new retaining wall. This paper discusses the working characteristics of self-embedded retaining wall in earthquake by using different reinforced scheme to simulate its seismic performance. SLIDE stimulates different reinforced scheme, which shows that the slope stability coefficient of horizontal reinforcement is larger than vertical watch reinforcement. The length and space of the reinforcement all influence the stability of the slope. The structural characteristics of self-embedded retaining wall shows that self-embedded retaining wall posses good seismic load transmission path and good seismic capacity. Firstly, the new self-embedded geotextile can effectively absorb seismic energy. Secondly, the movement of blocks, gravel filter layer and reinforced soil also plays an important role in energy consumption. Thirdly, high strength weight ratio can also reduce the seismic forces. Fourthly, gravel filter layer, geogrid and anchor rod which have a certain amount of damping force also posses good isolation performance. What’s more, anchor rods and geogrid which has a certain flexibility can restore to its original state within a certain time after the earthquake.
