搅拌桩和排水板堆载预压联合处理软土地基的应用研究

Applied Study on Treatment Soft Ground Combined with Mixing Pile and Drainage Board Preloading

本文提出搅拌桩深层处理和塑料排水板堆载预压法联合处理方法,利用有限元软件建立3种不同的堆载预压模型,对比分析各模型中地表沉降和土体内部水平位移,探讨在不同搅拌桩约束条件下土体固结的规律,并结合工程检测实例证明该处理方法的实用性和有效性。

This paper presents a method that associative action of mixing pile and drainage board preloading,and established the three rational finite element heaped load preloading models,and analyze ground surface settlement and horizontal displacement of soil body interior of each model,discussion on the regularity of soil consolidation under different mixing piles.The test result shows that the method is practical and effective.
