地铁下穿购物长廊爆破施工风险分析

Risk Analysis of Subway Blasting Construction under Shopping Promenade

地铁下穿购物长廊爆破施工项目周边的自然和社会环境复杂,包含了许多不确定性因素,会对工程项目的顺利实施产生风险,因此迫切需要对爆破施工项目进行风险的分析与控制。基于大连地铁2号线下穿某购物长廊的爆破施工项目,对项目的风险进行了识别与评估,并参照评估结果,提出了基于损失控制理念的减震爆破设计。该设计可为类似项目提供参考。

Subway blasting construction under a shopping promenade is often done in a complex natural and social environment, there are many uncertain factors that might result in risks directly affect the smooth construction of the project. So, risk analysis and control is urgently needed for the blasting construction project. Based on the blasting work under a subway shopping promenade on Dalian metro Line 2, the project risk assessment is carried out. By refering to the evaluation result, a cushion blasting design is proposed based on the concept of damage control. This design can provide a reference for similar projects.
