摘要

采用Biot固结理论分析了止水帷幕对基坑工程环境效应的影响，包括止水帷幕不同打设深度的效果，以及两种封闭式止水帷幕发生漏水意外时对地下水位和坑外土体位移的影响等。在有限元编程中，将开挖土体置为空气单元可以简化处理过程。算例分析结果表明，深厚透水地基中增加竖向止水帷幕的深度并不能有效减小对周围环境的影响；漏水部位周围土体的渗流等势线较为密集，渗流速度较大，容易诱发扩大破坏；竖向封闭式止水帷幕漏水引起的坑边土体的沉降和地表土体的侧移相对较大，水位下降迅速等。其结果可供基坑工程漏水事故环境效应的评价和对策研究时参考。

Abstract

Based on Biot’s consolidation theory

the effects of the performance of waterproof-wall in deep foundation-pit on surrounding environment are analyzed. The subject investigated deals with the effectiveness of the burying depth of waterproof-wall

the influence of water leakage in enclosed structures of waterproof-wall on ground water table and foundation displacement

etc. For purpose of convenience

the excavated soil is treated as the idealized air element in FEM programming. The results show that in the case of thick pervious subsoil

the increase of the burying depth of waterproof-wall can hardly decrease the effects of foundation-pit on surrounding environment. The dense contours of seepage potential around the location of leakage are found with high seepage velocity

liable to induce expanded destruction. The water leakage occurred in the perpendicularly enclosed waterproof-wall will lead to the outstanding increase of the magnitude of foundation settlement around pit margin and ground lateral-displacement

as well as the rapid drawdown

etc. The conclusions could be provided for the appraisal and solution strategies for the effects of water leakage on surrounding environment.
