潇湘船闸工程建设施工期基坑稳定性安全分析

    Safety analysis of foundation pit stability during the construction period of Xiaoxiang ship lock project

    • 摘要: 船闸基坑是工程施工期安全管控的关键,针对船闸基坑施工期的安全管控问题,进行深入分析。重点聚焦于船闸上下游围堰及基坑边坡的稳定性,确保工程在施工期间的安全性。研究综合考虑了地形、枢纽工程布置、通航条件、水文地质条件、施工条件、施工期通航影响、征地拆迁以及土石方开挖等多个关键因素,采用条分法对其上下游围堰和基坑边坡稳定性进行详细分析。研究结果为潇湘枢纽船闸改建工程在施工期间的主体基坑安全管控提供了科学依据,确保了工程的顺利进行和施工安全。

       

      Abstract: The foundation pit of the ship lock is the key to safety control during the construction period of the project. In depth analysis is conducted on the safety control issues during the construction period of the ship lock foundation pit. The focus is on the stability of the upstream and downstream cofferdams and foundation pit slopes of the ship lock,ensuring the safety of the project during construction. The study comprehensively considered multiple key factors such as terrain,hub engineering layout,navigation conditions,hydrogeological conditions,construction conditions,navigation impact during the construction period,land acquisition and demolition,and earthwork excavation. The stability of the upstream and downstream cofferdams and foundation pit slopes was analyzed in detail using the slice method. The research results provide a scientific basis for the safety control of the main foundation pit during the construction period of the Xiaoxiang hub ship lock reconstruction project,ensuring the smooth progress and construction safety of the project.
