摘要
近年来,在国家对城市空间优化利用力度加大的背景下,地下综合管廊项目在全国各地加速建设。本项目位于广州市南沙区,其特点是管廊结构在深厚的淤泥~淤泥质土软土层之上建造,软土层是管廊工程的一个需要特殊处理的工程问题,它决定了工程的成败和成本等一系列关键因素。论文结合工程地质勘察的实践经验,对所述项目工程区的软土工程地质特征进行了分析和总结,并对管廊工程对软土的治理提出了可行的地基基础方案。
In recent years,under the background that the state has strengthened the use of urban space,the construction of underground gallery is springing up all over the country.The project located in Nansha,Guangzhou.The gallery structure is built on the deep soft soil layer.The soft soil is an important object,which determines the success or failure of the project.In this article,it summarizes the geological characteristics of soft soil,and puts forward a feasible foundation scheme for the treatment of soft soil.It is hoped that the summary can provide reference for the engineering survey and design.
