【摘要】：近年来,我国公路隧道建设取得了蓬勃的发展。然而,隧道所处的环境较复杂,其中地下水环境尤为复杂,致使公路隧道在运营过程中病害频发,为隧道的安全运营带来很大隐患。其中,渗漏水是公路隧道最常见的病害之一。 本文以重庆高速公路运营隧道为工程依托,通过现场调研、资料分析和模糊数学等手段,对公路隧道渗漏水病害检测及评价体系进行了分析。本文的主要研究内容和成果如下： 1、结合重庆地区高速公路隧道调研资料,对公路隧道渗漏水影响因素进行了研究,建立了渗漏水影响因素指标体系,提出了渗漏水影响因素的四级划分标准。 2、分析了隧道常规检测方法中的传统检测方法和无损检测手段。比较了各种检测方法的优缺点及适用性。研究了隧道渗漏水各个指标的检测方法,制定了渗漏水病害专项检测表格。 3、选用模糊数学方法对隧道渗漏水进行综合评判,建立了公路隧道渗漏水病害评价体系。将隧道渗漏水病害按照严重程度划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ四个等级,隧道渗漏水评价作为目标层,自然条件因素、围岩及地下水因素、设计因素、施工因素和营运维护因素五个方面作为准则层,准则层下又分别有四个指标,即20个子因素作为指标层。通过两级模糊综合评判,利用最大隶属度原则得出隧道渗漏水等级。 4、编制了隧道渗漏水病害等级评价软件,可在日常隧道渗漏水病害评价工作中应用。选取正阳隧道作为隧道渗漏水病害评价算例,取典型区段进行综合评判,得出区段的渗漏水病害等级,评价结果符合现场实测的统计结果。
[Abstract]:In recent years, the highway tunnel construction in China has made vigorous development. However, the tunnel environment is more complex, especially the groundwater environment, resulting in the highway tunnel in the operation process of frequent disease. Water leakage is one of the most common diseases in highway tunnel. In this paper, based on Chongqing Expressway operating Tunnel, through field investigation, data analysis and fuzzy mathematics and other means, The detection and evaluation system of highway tunnel leakage disease is analyzed. The main research contents and results are as follows:. 1. Based on the investigation data of highway tunnel in Chongqing area, the influencing factors of leakage water in highway tunnel are studied, the index system of influencing factors of leakage water is established, and the four-level classification standard of influencing factors of leakage water is put forward. 2. The traditional detection method and the nondestructive testing method in the conventional tunnel detection method are analyzed. The advantages, disadvantages and applicability of the various detection methods are compared. The detection methods of each index of tunnel leakage are studied. A special inspection form for seepage diseases was established. 3. The comprehensive evaluation of tunnel leakage is carried out by using fuzzy mathematics method, and the evaluation system of tunnel leakage disease is established. The tunnel leakage disease is divided into four grades according to the severity of the disease: 鈪，
