摘要
针对分析堤防受邻近基坑开挖影响所产生变形的局限性,以同济大学初雨调蓄池基坑开挖为例,结合有限元强度折减法,扩展研究了临河深基坑对堤防边坡稳定性的影响;同时为堤防边坡稳定性的定量判别提供了新思路,使评判结果比现行规范要求更为全面合理.
Abstract
Aiming at the limitation of analyzing the deformation of the embankment caused by the excavation of the adjacent foundation pit,taking the foundation pit excavation of initial rainwater storage tank of Tongji University as an example,combined with the finite element strength reduction method,the influence of riverside deep excavation on the stability of embankment slope is extended and studied.The new idea for the quantitative discrimination of embankment slope stability is provided to make the judging result more comprehensive and reasonable than the current code requirements.
