摘要
粉喷桩具有施工进度快、费用低、操作简单、对环境影响小等优点 ;它适用于处理淤泥、淤泥质土、粉土和地基含水量较高且承载力较低的粘性土等 ,通过工程实践 ,介绍粉喷桩在特殊地层应用时 ,如何合理确定参数 ,优选施工工艺和方法 ,使复合地基承载力等指标满足设计要求。
The high pressure jet cement stabilized piles enjoy the advantages of quick construction,low cost,easy operation and little impact on environment. It is suitable for treatment of mud, muddy earth,silty earth and clay grounds with high water content and low bearing capacity.From the view point of engineering practice,the paper describes how to determine the parameters rationally,optimize construction technology and method and to enable the composite ground up to the design requirement for bearing capacity when it is applied in special strata.
