预应力管桩处理软弱地基是目前刚性桩复合地基的一种类型,应用效果需要工程实践的验证和总结。本文通过某小区管桩复合地基成果,经过检测成果、沉降观测结果与设计结果比较,探讨了在软弱地基采用预应力管桩进行地基处理的承载力设计方法、检测方式、复合地基承载力确定方法和变形设计经验系数,为地区类似工程提供了可借鉴的经验资料。 Prestressed pipe pile processing soft foundation is currently a type of rigid pile composite foundation, the application effect needs the verification and summary of engineering practice. In this paper, through comparing the results of test results and settlement observation results with the design results, this paper discusses the bearing capacity design method, testing method and method of bearing capacity of composite foundation with prestressed pipe piles in soft ground And deformation design experience coefficient, provide similar experience for similar projects in the region.
