新冯家口闸淤泥质软土地基的处理措施

Treatment Measures of Silt Soft Soil Foundation of Xinfengjiakou Gate

在工程建设中,经常会遇到淤泥类软土地基问题,由于软土地基具有压缩性高、强度低及均匀性差等特点,作为建筑物地基,一般都需要对其进行地基补强处理。在对新冯家口闸软土地基工程地质特性分析及处理措施总结的基础上,结合类似工程经验,对软土地基的工程地质特性、处理措施,以及软土地基处理过程中的常见问题进行了探讨。通过本工程的实践经验证明,采用水泥土搅拌桩处理软土地基以提高复合地基承载力是行之有效的办法,可在类似工程中推广使用。

In the construction of engineering,the soft soil foundation of silt is often encountered. As the soft soil foundation has the characteristics of high compressibility,low strength and poor uniformity,as the foundation of a building,foundation remedial treatment is usually required. On the basis of the analysis of the engineering geological characteristics and the treatment measures of the soft soil foundation of the Xinfengjiakou gate,this paper discusses the engineering geological characteristics and treatment measures of the soft soil foundation,as well as the common problems in the soft soil foundation treatment. Through the practical experience of this project,it is proved that it is an effective way to improve the bearing capacity of the composite foundation by using cement soil mixing pile,and it can be popularized and used in similar projects.
