砂质粉土地基地下连续墙施工工艺应用和研究

Application and Study of Sandy Silt Foundation Underground Continuous Wall Construction Technology

在砂质粉土地基,尤其是在新淤积粉土地基上进行地下连续墙施工是一项重大的技术难题。本文结合工程实践,介绍砂质粉土地基地下连续墙施工工艺,并针对特殊地基,详细描述并总结了施工方案的控制要点,以期为类似工程施工提供借鉴经验。

Underground continuous wall construction on sandy silt foundation, especially on new filled-up silt foundation is a major technical challenge. The paper combines engineering practice to introduce sandy silt foundation underground continuous wall construction technology. The control key points of construction program are described and summed up in details aiming at special foundation thereby providing reference experience for construction of similar projects.
