【摘要】：近年來,隨著公路營(yíng)運(yùn)隧道數(shù)量和里程逐年增加,隧道在營(yíng)運(yùn)過程中暴露病害愈加頻繁。在眾多隧道病害中,隧道滲漏水病害因其分布范圍廣、危害程度高、治理難度大等特點(diǎn)備受關(guān)注。因此開展隧道滲漏病害的產(chǎn)生機(jī)制以及滲漏病害的處治方法研究就顯得十分急迫。 本文以重慶地區(qū)出現(xiàn)嚴(yán)重滲漏水病害的公路隧道為工程背景,歸納總結(jié)了巖溶地區(qū)隧道滲漏病害分布特征,揭示了隧道滲漏水病害成因�；跀�(shù)值模擬手段,探討了巖溶地區(qū)公路隧道滲漏水病害形成機(jī)制,并開展了針對(duì)性的滲漏病害處治原則及措施研究。研究?jī)?nèi)容和成果如下： (1)基于對(duì)重慶地區(qū)15座滲漏水病害較為嚴(yán)重的營(yíng)運(yùn)高速公路隧道相關(guān)資料的整理分析,定量的評(píng)價(jià)了其滲漏病害的嚴(yán)重程度。探明了隧道滲漏水病害的時(shí)間和空間分布規(guī)律,揭示了其滲漏病害成因。 (2)引入溫度場(chǎng)比擬滲流場(chǎng)的方法,從隧道襯砌水壓分布規(guī)律和支護(hù)結(jié)構(gòu)安全性能兩方面,探討了巖溶地區(qū)降雨引起的地下水位變化、充水性巖溶裂隙(管道)、隧道排水系統(tǒng)劣化所導(dǎo)致的滲漏病害的發(fā)生發(fā)展機(jī)制。 (3)根據(jù)隧道病害區(qū)段襯砌是否承受水壓,將隧道滲漏病害分為承壓帶滲漏病害和非承壓帶滲漏病害。結(jié)合巖溶地區(qū)公路隧道滲漏病害的時(shí)空分布特點(diǎn)和滲漏病害發(fā)生發(fā)展機(jī)制,分別研究了承壓帶滲漏病害和非承壓帶滲漏病害的處治原則和處治措施。
[Abstract]:In recent years, with the increasing number and mileage of highway operating tunnels, more and more tunnel diseases are exposed. Among many tunnel diseases, tunnel leakage disease has attracted much attention because of its wide distribution, high degree of harm and difficulty in treatment. Therefore, it is urgent to study the mechanism and treatment of tunnel leakage disease. In this paper, based on the engineering background of highway tunnel with serious leakage disease in Chongqing area, the distribution characteristics of tunnel leakage disease in karst area are summarized, and the causes of tunnel leakage disease are revealed. Based on the method of numerical simulation, the formation mechanism of leakage disease of highway tunnel in karst area is discussed, and the principles and measures of dealing with leakage disease are studied. The research contents and results are as follows: (1) based on the analysis of the related data of 15 serious seepage diseases in Chongqing, the degree of leakage is quantitatively evaluated. The temporal and spatial distribution law of tunnel leakage disease is proved, and the cause of seepage disease is revealed. (2) the method of comparing seepage field with temperature field is introduced, from two aspects of tunnel lining water pressure distribution law and supporting structure safety performance, This paper discusses the groundwater level change caused by rainfall in karst area, the occurrence and development mechanism of leakage disease caused by water-filled karst fissure (pipeline) and tunnel drainage system deterioration. (3) according to whether the lining of tunnel disease section bears water pressure, Tunnel leakage disease is divided into confined zone leakage disease and non-pressure band leakage disease. Combined with the characteristics of space-time distribution and the mechanism of occurrence and development of leakage disease of highway tunnel in karst area, the principles and measures of treatment of leakage disease in confined zone and non-confined zone are studied respectively.
