高速公路桥头深厚软土地基的水泥搅拌桩处理

Processing Deep Mollisol Foundation in Expressway Bridge Abutment by Cement Mixing Pile

通过某高速公路桥头深厚软土路基处理实例,分析比选软基拓宽处理方案,重点介绍水泥搅拌桩设计及施工技术。观测效果表明,该处理处治措施能较好地控制软土路基沉降,防治桥台跳车病害。

By using the processing example of deep expressway mollisol foundation in an expressway bridge abutment, the analysis and selection has been carried out to mollisol foundation widening scheme, and mainly in- troduced design and construction technology of cement mixing pile. The observation results show that, the pro- cessing measures can better control the settlement of mollisol subgrade, prevent abutment jump disease.
