摘要
稞老湾梁隧道因建设年代较早,隧道防排水和防冻措施不完善,隧道渗漏水和衬砌裂损病害严重,气温较低时路面常出现大面积结冰现象,影响交通安全。根据现场调查和专项检测结果,对隧道的技术状况和安全性进行评价。借鉴以往处治经验,本文提出“钢筋混凝土套衬加固+增设仰拱+重建隧道防排水系统”方案对隧道病害进行处治。
The construction age of Kelaowanliang tunnel is early,the tunnel anti-drainage,anti-freezing measures are not perfect,tunnel leakage,lining cracks and diseases are serious,when the temperature is low,the road surface has a large area of ice,which seriously affects the traffic safety.According to the results of field investigation and inspection of the tunnel,the technical condition and safety evaluation of the tunnel were carried out,and the scheme of reinforced concrete lining reinforcement+adding invert+rebuilding tunnel anti-drainage system was put forward for the treatment of tunnel diseases.
