钓鱼台隧道洞口崩塌成因分析与处治措施研究
摘要:对池祁高速钓鱼台隧道洞口大型崩塌的成因进行了深入分析，提出了相应的崩塌处治措施，并通过现场监测分析对崩塌处治效果进行了验证。研究结果表明，钓鱼台隧道洞口崩塌是地形、地质、降雨、施工措施不当等多种因素共同作用的结果，其中地形和地质条件是形成崩塌的内因，降雨和施工措施不当等因素是诱发崩塌的外因。基于以上影响因素并结合隧道洞口实际情况，提出了“临时支护+永久性防护”的综合处治方案，即采用洞内背拱加固、掌子面反压回填、崩塌体卸载、洞口双层小导管支护、接长明洞以及洞顶仰坡锚杆框架防护的方案。现场巡视与监测数据表明，隧道洞口崩塌处治措施得当，工程效果显著，实现了预期目的。
Abstract:An in-depth analysis was conducted on the causes of the collapse at the entrance of the Diaoyutai Tunnel on the Chi-Qi Expressway, and corresponding measures for dealing with the collapse were proposed. The effectiveness of the collapse treatment was verified through on-site monitoring and analysis. The research results indicate that the collapse of the Diaoyutai Tunnel entrance is the result of a combination of various factors such as terrain, geology, rainfall, and improper construction measures. Among them, terrain and geological conditions are the internal factors that cause the collapse, while rainfall and improper construction measures are the external factors that induce the collapse. Based on the above influencing factors and combined with the actual situation of the tunnel entrance, a comprehensive treatment plan of temporary support+permanent protection has been proposed, which includes reinforcement of the tunnel arch, backfilling of the tunnel face with back pressure, unloading of the collapsed body, double layer small conduit support at the entrance, extension of the open cut tunnel, and protection of the roof and forward slope anchor rod frame. The on-site inspection and monitoring data indicate that the treatment measures for tunnel entrance collapse are appropriate, and the engineering effect is significant, achieving the expected purpose.
