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。
In view of the collapse of foundation pit in a metro station in Beijing, the reasons for the collapse of the foundation pit are analyzed from the surrounding environment, design and construction. The design and construction of the future foundation pit should be strengthened in the following aspects: Of the information construction, improve the monitoring project and the alert value, through remote monitoring and control, to achieve timely feedback and processing of information; in the process of construction of the pit, to enhance the exploration of the laws of space and time; pay attention to the surrounding environment of the pit to detect and promptly eliminate various security risks The method of dynamic design was used to establish the dynamic management system of foundation pit and strict management process to realize the standardization and scientification of the construction of foundation pit.
