软基处理中水泥土搅拌桩设计参数的影响分析

On influential analysis of design parameter of cement mixing method of soft foundation treatment

根据水泥土搅拌桩的特点及工作机理,结合计算案例,对水泥土搅拌桩在地基处理中桩径、桩长、桩间距主要参数对软土地基处理的效果影响进行了对比分析,验证了增加桩长比扩大桩径和减小桩间距更能控制沉降变形、节约工程造价的理论。

According to the features and working principle for the cement mixing pile,the paper undertakes the comparative analysis of the main parameter,such as the pile diameter,pile length,and pile distance,on the treatment effect of the soft foundation in the cement mixing pile con-struction,and proves the added pile length can control the settlement deformation and save engineering cost in a better way than the enlarged pile diameter and reduced pile distance.
