摘要
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。
This thesis introduces the situation of gushing water and mud or secondary tunnel-liner fracture disease at 1st right Xiatangkou Hole of Yuxiang speedway tunnel K23＋187.5～199.5 m and YK23＋201～210 m.Based on ground-penetrating radar and principles of selective basis,using ground-penetrating radar and non-destructive detection technique to detect and diagnose the gushing water and gushing mud and second lining fracture disease.According to the diagnose of diseases and their reasons,this thesis proposes a disease treatment program and provides a reliable technical support.Through the optimized treatment,the positive result is significant.
