建筑工程中深基坑支护施工技术分析

Analysis on Construction Technology of Deep Foundation Pit Support in Construction Engineering

以贵港市覃塘区棚户区改造工程为背景,结合其岩土工程勘察报告,介绍了临近水渠的深基坑开挖过程中支护措施,即高压旋喷桩封水帷幕(水渠侧)、放坡+土钉墙。并借助理正岩土软件,分别验算了其局部抗拉、内部稳定性、外部稳定性、喷射混凝土面层等内容,结果都满足相关要求,为类似工程提供一定的参考价值。

Taking the shantytown reconstruction project in Qintang District of Guigang City as the background,combined with its geotechnical engineering survey report,this paper introduces the supporting measures during the excavation of the deep foundation pit near the canal,that is,the high-pressure jet grouting pile sealing water curtain(the side of the canal).And with the help of Lizheng geotechnical software,the local tensile strength,internal stability,external stability,sprayed concrete surface and other contents were checked and calculated.The results all met the relevant requirements and provided certain reference value for similar projects.
