筋材台阶式挡墙拟静力地震稳定性研究
Study on Pseudo-static Seismic Stability of Reinforced Retaining Walls with Step-shaped Backfill
摘要
Abstract
To analyze the seismic stability of retaining walls with step-shaped reinforcement arrangements,a pseudo-static study on reinforced soil retaining walls was conducted using the finite element limit analysis method combined with the strength reduction technique.The results show that,compared to the results obtained from the limit equilibrium method,the proposed approach yields predictions closer to those measured in shaking table model tests.A step-shaped reinforcement arrangement is recommended when the average reinforcement length exceeds 0.7 times the wall height,the wall height does not exceed 6 m,and the vertical spacing is relatively small.Using an excessively large dilatancy angle tends to overestimate the effectiveness of the step-shaped reinforcement layout,especially when there is a significant variation in reinforcement length along the wall height.关键词
