超大断面隧道施工安全风险分析及控制研究

Safety Risk Analysis and Control of Super-large Section Tunnel Construction

超大断面隧道施工安全风险高,如果控制不当极易引发隧道施工安全事故,因此开展施工安全风险分析对确保超大断面隧道施工安全具有重要意义。依托中开高速公路大常山超大断面隧道项目,揭示隧道施工风险事故与风险源之间的关系,基于层次分析法和专家调查法,开展施工阶段隧道风险源辨析和评估,并提出相应控制对策。相关研究为超大断面隧道施工风险的有效预防和评估提供依据,从而有效避免隧道施工安全事故的发生。

The construction safety risk of super-large section tunnel is high,and it will easily cause tunnel construction safety accidents if the safety risk is not controlled properly.Therefore,carrying out construction safety risk analysis is of great significance to ensure the tunnel construction safety of super-large section tunnel.The relationship between tunnel construction risk accidents and risk sources are reveled aiming at the Dachangshan Super-large Section Tunnel of Zhongshan-Kaiping Expressway.Based on the analytic hierarchy process,the risk sources of tunnel in the construction stage are discriminated and evaluated.The corresponding control measures are put forward to provide the basis for the effective prevention and evaluation of the construction risk of super-large section tunnel,so as to avoid the occurrence of tunnel construction safety accidents to the greatest extent.
