摘要
临近地铁的基坑项目在开挖过程中,随着其土体应力状态的改变,会造成基坑失稳或对周围既有建筑结构和环境造成不利的影响,为保证项目的顺利施工和维持现有地铁的安全运行状态,需要对基坑工程的安全可行性和对既有地铁自身结构进行及时全面的监测。本文以实际项目作为依托,对地铁相关结构进行实际监测,通过监测数据与数值模拟结果的对比分析对地铁附属结构进行安全分析。
With the change of the stress state of the soil in the excavation process of the foundation pit project near the subway,,it will cause the instability of foundation pit or adversely affect on the surrounding structures and environment,in order to ensure the smooth construction of the project and maintain the safety of the existing metro running state,need The feasibility and safety of the foundation pit engineering for timely and the existing subway structure need be roubdly monitored.In this paper,based on the actual project,the actual monitoring of related structures of subway is carried out,and the safety analysis of accessory structures of subway is carried out by comparing the monitoring data with the numerical simulation results.
