旋喷搅拌加劲桩在市政线型基坑工程中的应用

The Application of Rotary Jet Mixing Stiffened Pile in Municipal Linear Foundation Pit Engineering

以呼和浩特市某新建地道工程为例,重点分析了旋喷搅拌加劲桩与常规支护形式的优缺点,并进行了支护体系的验算分析,为同类工程基坑设计方案的比选及确定提供参考。

This article takes a newly built subway project in Hohhot as an example, analyzes the advantages and disadvantages of rotary jet mixing stiffening piles and conventional support forms, and carries out checking calculation analysis of the supporting system, to provide reference for the comparison and determination of the design scheme of similar engineering foundation pit.
