现浇混凝土薄壁管桩复合地基技术研究

Study on Cast-in-situ Concrete Thin-wall Tabular-pile Composite Foundations

在分析常用的软土地基加固技术适用性和局限性的基础上,详细介绍现浇混凝土薄壁管桩复合地基处理方法的加固机理、设计、施工、检测方法等,提出路基“拱效应”、土工格栅“拉膜效应”新观点,结合实例讲述现浇薄壁管桩处理地基的优越性、经济性。

On the basis of analysis of the adaptability and limitation of the softsoil foundation consolidating technology, frequently used, treatment of the cast-in-situ concrete thin-wall tubular-pile composite foundations is elaborated as to its consolidating mechanism, design, construction and inspection and measurement. The new viewpoints of the arch effect of foundations and earth-work lattice stiffening effect are put forward. Practical application is included to illustrate the superiority and economy feature of foundation treatment by means of cast-in-situ concrete thin-wall tubular piles.
