某特长山岭隧道涌水突泥施工安全专项风险评估研究

Special Risk Assessment Studyon Construction Safety of Water Gushing and mud Outburst in aExtra-longMountain Tunnel

山岭隧道施工工艺复杂,施工组织实施困难,安全问题突出。以某公路特长山岭隧道为例对岩溶发育、富水性强的特长山岭隧道进行了涌水突泥施工安全专项风险评估研究,根据评估结果对该隧道预防涌水突泥施工风险提出针对性的防控措施,为同类隧道施工风险评估提供参考。

The construction technology of mountain tunnels is complex,the construction organization and implementation are difficult,and the safety problems are prominent.Taking aextra-long mountain tunnel as an example,the special risk assessment of water gushing and mud bursting construction safety of the extra-long mountain tunnel with karst development and rich water was studied.According to the assessment results,the corresponding provention and control measures are put forward to prevent the construction risks of water gushing and mud bursting,which provides a reference for the construction risks assessment of similar tunnels.
