摘要
基于某工程实例,阐述了采用树根桩作为主控桩、水泥土搅拌桩作为辅桩,共同发挥作用的双桩型复合地基承载力设计计算方法;通过经济分析表明,双桩型复合地基在一定程度上具有更好的经济性和适用性;通过对该实例的分析,得出了一些建议性的结论,可供类似工程设计参考.
Based on a project example,this paper shows the design of the composite piled foundation and the calculation methods of the bearing capacity of the foundation with tree root as the master pile and the cement-soil pile as auxiliary pile.And then through the economic analysis the paper shows that the composite piled foundation to some extent has better eco-nomic efficiency and applicability.Finallyt,hrough the example analysis the paper draws some constructive conclusionst,hus providing reference for engineering designers.
