旋喷桩复合地基设计几个计算参数的探讨

Discussion on design parameters for jet grouting pile composite foundation

旋喷桩复合地基设计包括桩径设计、布孔形式、孔距确定、单桩承载力及复合地基承载力计算等,设计计算参数的确定是从工程的经济效益和技术可行性考虑,并结合当地工程地质和水文地质条件等因素进行综合选择的。文章根据桂林地区的具体情况,就旋喷桩复合地基设计的几个计算参数作简要的探讨。

The designs of composite foundation for jet grouting pile include pile size, hole laying out, hole interval, calculation of weight bearing capacity for single pile and that for composite foundation, etc. The design parameters are determined in terms of project economical efficiency, technical feasibility, engineering geology and hydrogeological conditions. An introduction to the parameter calculation for jet grouting pile composite foundation is presented based on case study in Guilin.
