摘要
基于对危险源的概念、引发机理等理论调研和分析,结合实际工程,系统分析四川仁沐新高速公路马边河2号桥桩基施工中可能出现的危险源,主要包括边坡坡脚拌合站附近裂缝、储料仓墙体裂缝、边坡清方后坡表溜坍、隧道洞口上方危岩等重大危险源,以及影响施工安全的从业人员等其他各种复杂因素,相关研究可为下一步的施工安全保障措施制定提供参考。
Based on the theoretical investigation and analysis of the concept and trigger mechanism of hazard sources,the possible danger sources in the pile foundation construction of Mabianhe No. 2 Bridge of Renmu New expressway in Sichuan are analyzed in this paper,such as cracks near the mixing station of the slope foot,cracks in the wall of the storage silo,surface sliding after slope clearin,dangerous rocks above the tunnel entrance,and other complicated factors affecting construction safety,etc.. The research can provide targeted guidance for the development of the next step in construction safety assurance.
