摘要
为掌握公路隧道衬砌渗漏水病害特征,结合杭州市27座公路隧道检测数据,对衬砌结构渗漏水特征及成因进行研究。研究结果表明:衬砌渗漏水以浸渗为主,约占总量的87%;衬砌渗漏水主要分布在衬砌裂缝和衬砌三缝处,且渗漏水位于三缝处的严重程度要高于衬砌裂缝位置。在此基础上分别对衬砌裂缝和三缝位置渗漏水成因进行了探讨,并给出了不同类型衬砌渗漏水的治理措施建议。
In order to master the characteristics of the lining leakage of highway tunnel,this paper studies the characteristics and causes of the leakage of lining structure based on the inspection data of 27 highway tunnels in Hangzhou. Theresults show that infiltration is the main part of lining leakage,accounting for 87% of the total amount. The leakage is mainlydistributed in the lining cracks and the three joints of thelining, and the severity of the leakage water in the three jointsis higher than that of the lining cracks. On this basis, thecauses of the leakage in the lining cracks and the three jointswere discussed, and suggestions for the treatment measuresfor different types of lining leakage were given.
