【摘要】：近年來,我國公路隧道建設(shè)取得了蓬勃的發(fā)展。然而,隧道所處的環(huán)境較復(fù)雜,其中地下水環(huán)境尤為復(fù)雜,致使公路隧道在運(yùn)營過程中病害頻發(fā),為隧道的安全運(yùn)營帶來很大隱患。其中,滲漏水是公路隧道最常見的病害之一。 本文以重慶高速公路運(yùn)營隧道為工程依托,通過現(xiàn)場調(diào)研、資料分析和模糊數(shù)學(xué)等手段,對公路隧道滲漏水病害檢測及評價(jià)體系進(jìn)行了分析。本文的主要研究內(nèi)容和成果如下： 1、結(jié)合重慶地區(qū)高速公路隧道調(diào)研資料,對公路隧道滲漏水影響因素進(jìn)行了研究,建立了滲漏水影響因素指標(biāo)體系,提出了滲漏水影響因素的四級劃分標(biāo)準(zhǔn)。 2、分析了隧道常規(guī)檢測方法中的傳統(tǒng)檢測方法和無損檢測手段。比較了各種檢測方法的優(yōu)缺點(diǎn)及適用性。研究了隧道滲漏水各個(gè)指標(biāo)的檢測方法,制定了滲漏水病害專項(xiàng)檢測表格。 3、選用模糊數(shù)學(xué)方法對隧道滲漏水進(jìn)行綜合評判,建立了公路隧道滲漏水病害評價(jià)體系。將隧道滲漏水病害按照嚴(yán)重程度劃分為Ⅰ、Ⅱ、Ⅲ、Ⅳ四個(gè)等級,隧道滲漏水評價(jià)作為目標(biāo)層,自然條件因素、圍巖及地下水因素、設(shè)計(jì)因素、施工因素和營運(yùn)維護(hù)因素五個(gè)方面作為準(zhǔn)則層,準(zhǔn)則層下又分別有四個(gè)指標(biāo),即20個(gè)子因素作為指標(biāo)層。通過兩級模糊綜合評判,利用最大隸屬度原則得出隧道滲漏水等級。 4、編制了隧道滲漏水病害等級評價(jià)軟件,可在日常隧道滲漏水病害評價(jià)工作中應(yīng)用。選取正陽隧道作為隧道滲漏水病害評價(jià)算例,取典型區(qū)段進(jìn)行綜合評判,得出區(qū)段的滲漏水病害等級,評價(jià)結(jié)果符合現(xiàn)場實(shí)測的統(tǒng)計(jì)結(jié)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，
