摘要
针对北京某地铁车站基坑坍塌事故,从周边环境、设计及施工等因素分析引发基坑坍塌的原因,提出未来基坑设计及施工需从以下几个方面加强,防患于未然:进行基坑的信息化施工,完善监测项目及警戒值,通过远程监控,实现信息的及时反馈与处理;在基坑施工过程中,加强时空规律的探索;注意基坑周围环境探测,及时消除各种安全隐患;采用动态设计的方法,建立基坑动态管理体系及严格的管理流程,实现基坑施工的规范化、科学化。
Possible reasons for the collapse occurring on a Beijing subway station were analyzed m terms of surrounding environment and design. The design and construction of the foundation pit should be strengthened in the following aspects in the future: adopting information construction of the foundation pit; improving monitoring and warning values; giving timely feedback and dealing with information through remote monitoring;, grasping space-time role in the process of the foundation pit construction; enhancing the exploration of the surrounding environment of the foundation pit and eliminating all kinds of security hidden troubles in time; adopting dynamic design methods to establish the dynamic management system and strict management procedures to achieve standard and scientific construction of the foundation pit.
