超深连续墙槽壁侧向变形影响因素分析

Analyses of the Affecting Factors on the Lateral Deformation of a Deep Diaphragm Wall Pit

随着地下工程的深基坑工程日渐增多、深度加大,作为其围护结构的地下连续墙施工技术越来越得到重视和广泛应用。结合黄河地质条件,从泥浆重度、泥浆液面高度、地下水、地面荷载及超深导墙五个方面,分析和计算对连续墙的侧向变形影响,提出超深连续墙槽壁稳定的工程措施。

With the development of subterranean projects, deeper diaphragm walls appeared and the construction technology of diaphragm walls has become a subject of common concern and has been adopted widely.This article analyzed and calculated the effects of five factors on the lateral deformation of diaphragm walls： Yellow River soil conditions, betonite weight, depth of betonite paste, underground water, surface surcharge and deep guiding walls. In consequence, the construction measures for diaphragm walls are presented.
