摘要
基于工程实际,介绍了相邻大型基坑同步开挖施工的支护设计。为安全计,设计采用了交界区域预留土坡的方式,以为相邻基坑的支撑提供后靠力,同时采用岩土工程软件分析了相邻基坑交界区域土坡的稳定性。实践证明,该方案是有效的,可为类似工程的设计和施工提供借鉴。
Based on engineering practice,the design of support for synchronous excavation of adjacent large foundation pits is introduced.For the sake of safety,the method of reserving soil slope in the junction area is adopted to provide back force for the support of adjacent foundation pits,and the stability of soil slope in the junction area of adjacent foundation pit is analyzed by geotechnical engineering software at the same time.The practice proves that the scheme is effective and can provide reference for the design and construction of similar projects.
