摘要
大连地铁202标段促春站暗挖区间穿越东联路桥基工程,涉及工程沿线地质、周边环境、开挖、支护及监测等综合施工过程,施工条件和环境复杂。运用综合模糊评价法建立了适合施工环境特点和暗挖工法的风险指标体系,对促春区间隧道施工进行分析风险评估,评估结果与工程实际相符。该风险评估方法对促春区间暗挖安全施工具有指导意义,对类似的工程具有一定的借鉴作用。
The Dalian subway 202 excavation of Cuchun tunnel through pile foundation of viaduct project of Donglian road is a comprehensive construction process which includes the engineering geology,surrounding environment,excavation,support and monitoring,complex construction conditions and environment.Risk index system is established for the environmental characteristics of construction and excavation method by using the fuzzy comprehensive evaluation method,and risk evaluation of tunneling in Cuchun is carried out and the evaluation result is consistent with the engineering practice.This risk evaluation method has guiding significance for excavation construction safety of Cuchun,which has a certain reference value for similar engineering.
