论文根据渝湘高速下塘口一号隧道右洞YK23+187.5~199.5 m和YK23+201~210 m里程段岩溶突水、突泥及二衬断裂病害情况;在初步分析岩溶突水、突泥及二衬断裂病害原因基础上,从探地雷达探测基本原理及探测频率影响基础理论出发,采用探地雷达无损探测技术来探测和诊断隧道突水、突泥及二衬断裂病害原因,技术上可行并取得了明显的探测效果。再根据探测诊断的病害具体情况及原因提出合理的病害处治方案,为隧道病害处治提供可靠技术支持,在优化处治方案下进行有针对性处治,效果明显。
According to the conditions of karst inrush, mud and lining faults in the YK23 + 187.5-199.5 m and YK23 + 201-210 m tunnels in the Xiaotang 1 tunnel of Yuxiang high-speed tunnel, the karst inrush, Based on the basic theory of GPR detection and the basic theory of the influence of detection frequency, the non-destructive detection of ground penetrating radar is used to detect and diagnose the causes of water inrush, mud and lining faults in tunnels. Technically, Feasible and achieved significant detection results. According to the specific conditions and causes of disease detection and diagnosis, put forward a reasonable disease treatment program, provide reliable technical support for the treatment of tunnel disease, targeted treatment under the optimized treatment plan, the effect is obvious.
