深基坑施工中的危险源辨识及控制

Identification and control of hazard sources in deep foundation pit construction

主要以深基坑开挖的重大危险源辨识为主要探讨对象,从基坑工程设计、专项方案、土方开挖、排水降水、坑边堆载、变形监测、应急措施等方面辨识危险源,分析其可能导致的事故和采取的对策措施,阐述危险源监测预警在基坑施工安全起到指导的作用。

The main major hazards identification in deep foundation pit excavation in this paper as the main study object,from foundation pit engineering design,special solution,precipitation,earth excavation drainage pit heap load,deformation monitoring,emergency measures to identify hazards,analyze the possible cause of accident and to take countermeasures,this paper hazards monitoring and early warning to play a guidance role in the foundation pit construction safety.
