水泥搅拌桩加固软土地基设计参数优化分析

Analysis on Optimization of Design Parameter for Soft-soil Foundation Stabilization with Cement Mixing Pile

结合云南某高速公路典型的工程地质特点及工程实例，论述了水泥搅拌桩处理软土路基沉降的计算方法，提出在进行沉降分析和沉降控制的基础上，对软土地基处理的设计方案进行分析和选择，特别是探讨了桩长和桩间距的选择等问题，对不同设计方案在沉降控制等方面进行分析和比较，对工程实际有一定的指导作用。

Based on the typical project geologic features of one highway in Yunan and the actual project example, the paper discusses the computing method for settlement of the soft-soil foundation stabilized with cement mixing pile. It proposes to analyze and select the design scheme on treatment of soft-soil foundation treatment based on the settlement analysis and control, discusses the matters concerning pile length and space between piles in particular, compares and analyzes the settlement controls in different design schemes, which has some instructive effect on project.
