涌泥涌沙隧道施工风险评估分析

Risk Assessment and Analysis of Mud Gushing and Sand Gushing Tunnel Construction

摘要: 涌泥涌沙作为复杂地质环境下隧道工程重大的风险一直是人们比较重视的问题，本文通过对拱桥铺隧道岩溶段的长期研究和检测，充分利用风险因素核对表法和风险评估的层次分析法对隧道施工中存在的风险进行识别和评估，并对高度施工风险，比如塌方、涌泥、涌沙、大变形提出了相应的控制措施，并对残余风险状况进行评估，确保将风险水平降低至低度以下，保证施工的安全进行，为类似的重难点隧道工程风险处理和安全施工提供了一定的参考价值。

Abstract: Mud gushing and sand gushing, as major risks of tunnel engineering in complex geological envi-ronment, have always been problems that people pay more attention to. Through long-term re-search and detection of Karst Section of arch bridge paving tunnel, risk identification and risk as-sessment of tunnel are carried out by using risk factor checklist method and analytic hierarchy process, and relative control measures are put forward towards high risk such as landslide, mud gushing, sand gushing and large deformation. The residual risk situation should be evaluated to ensure that the risk level is reduced to below a low level and the construction safety is guaranteed, which provides a certain reference value for risk treatment and safe construction of similar difficult and difficult tunnel projects.
