旋喷桩和搅拌桩复合地基设计探讨

Design Discussion for Compound Foundation of Circle Jet Pile and Mixing Pile

基于工程实践和复合地基承载力的基本公式，采用反推法来设计高压旋喷桩和深层搅拌桩复合地基，确定经济合理的有效桩长和面积置换率，经多个工程实践，显示有较好的应用价值．

Based on engineering practice and basic formula of composite foundation strength to using reverse calculation method of designing composite foundation of high pressure circle jet pile and depth mixing pile, the economical and rational effective pile length and area replacement ratio are defined. This method application value is better.
