特殊地质条件深基础地下连续墙施工应用研究

为了有效解决软土地区复杂地质条件情况下深基础地下连续墙防护工程经常遭遇槽壁坍塌及容易引发透水性事故等施工难题,本文针对复杂地质情况、周围建筑物的稳定性安全要求及管线影响等众多制约因素,结合深圳某地下工程施工实践进行经验总结,提出特殊地质条件下的深基础地下连续墙的施工参数及施工工艺控制措施,分析和归纳得出控制好材料质量、泥浆护壁及控制导墙和导坑的施做工艺是施工成败的关键的结论。为今后类似工程提供借鉴。

Research of Diaphragm Wall Construction in Deep Foundation under Special Geological Conditions

In order to effectively solve the problems about deep diaphragm wall protection which often suffers the collapse of vessel wall and accident in construction under complex geological conditions of soft soil foundation,according to complex geological conditions,the stability safety requirements of surrounding buildings and pipelines and other restricting factors,combined with the experience of an underground construction in Shenzhen,this paper comes up with the construction parameters and measures to control the construction quality of the continuous wall beneath special geological conditions,and puts forward the verdict that to dominate the quality of materials,mud protection and the guide walls’ drift process is the key to construction success through summarizing and analyzing,thus to provide a reference for future similar projects.
