-
摘要: 通过北京某工程实例,介绍深坑回填土工程所采用的素土回填分层强夯和CFG桩复合地基联合地基处理设计,同时通过后期沉降观测资料分析,证明该联合方法对该坑填工程是切实可行和经济合理的,为类似坑填工程项目的设计应用提供了成功的范例。Abstract: Through a project example of Beijing,introduces united foundation treatment design of the soil backfill of dynamic compaction in layers and CFG pile composite foundation in the pit backfill engineering,and through the late settlement observation data analysis proves that the method is feasible and economic reasonable of the pit engineering,provides a successful example of application in design the project is similar to the pit.
