“桩墙合一”技术在深基坑工程中的应用

Practice of Dual-purpose Pile Wall Technique in Deep Foundation Engineering

“桩墙合一”结构体系在工程实际中已经有了少量的应用。为了验证新技术在实际工程中的合理性与安全性,基于合肥市某雨水调蓄池深基坑工程对“桩墙合一”技术的结构设计方法、施工方法进行阐述,对施工全过程进行阶段性监测并分析实际监测结果,取得了良好的效果,证明了该技术在实际工程中是适用的、成熟的。同时可以为“桩墙合一”技术在以后实际工程中的应用提供借鉴依据。

The dual-purpose pile wall structural system has a small number of applications in engineering practice.In order to verify the rationality and safety of the new technology in the actual project,based on the deep foundation pit project of a rainwater storage tank in Hefei,the structural design method and construction method of the dual-purpose pile wall technology are explained,and the whole construction process is carried out.Phased monitoring and analysis of actual monitoring results have achieved good results,proving that the technology is applicable and mature in actual engineering.At the same time,it can provide a reference for the application of the dualpurpose pile wall technology in future practical projects.
