市政道路软土地基处理对策分析

Analysis on Treatment Measures for Soft Soil Foundation of Municipal Roads

合理的软土地基工程处理方式不仅能节约大量工程造价,更能加快工程施工进度,提高项目的建设经济效益。文章介绍了常见的软土地基处理方式及控制要点,并以长望路西延线道路软基处理为例,采用分层总和法计算了地基加固前后的沉降值,结果表明:采用水泥搅拌桩能有效减少软土地基70%~80%的沉降,为软土地基处理提供了借鉴。

Reasonable soft soil foundation engineering treatment method can not only save a lot of engineering cost,but also accelerate the engineering construction progress and improve the economic benefits of the project.This paper introduces the common soft soil foundation treatment methods and control points.Taking the soft foundation treatment of Changwang Road West Extension Line as an example,the settlement value before and after foundation reinforcement is calculated by using splitting summation method.The results show that the use of cement mixing piles can effectively reduce the settlement of soft soil foundation by 70%-80%,which provides a reference for soft soil foundation treatment.
