摘要
文中以驸马庄棚户改造工程为例,结合地质勘察资料,采用"土钉墙+挂网喷浆"复合支护技术,按照分层开挖、层层支护的原则确保深基坑开挖任务顺利完成.从沉降观测情况看,最大累积沉降量为18.5 mm,在允许范围内,工程实践取得了良好的支护加固效果,为深基坑开挖与支护提供了参考.
Abstract
Taking the Fumazhuang shantytown renovation project as an example,combined with geological survey data,the composite support technology of"soil nail wall+hanging net spraying"was adopted.According to the principle of layered excavation and support,the deep foun-dation pit excavation task was successfully completed.From the settlement observation,the maximum cumulative settlement was 18.5 mm,which achieved good support and reinforcement effect within the allowable range,providing reference for deep foundation pit excavation and support.
