【摘要】：隨著我國(guó)西部山嶺重丘地區(qū)長(zhǎng)、大、深埋隧道的大規(guī)模修建,隧道施工過程中穿越地段的水文-工程地質(zhì)背景越來越復(fù)雜。為了保證安全、高效的進(jìn)行隧道施工,超前地質(zhì)預(yù)報(bào)工作就顯得極其必要。本文主要是結(jié)合西成客運(yùn)專線大秦嶺隧道水文地質(zhì)、工程地質(zhì)背景資料來對(duì)隧道超前地質(zhì)預(yù)報(bào)工作進(jìn)行分析研究的。研究?jī)?nèi)容主要圍繞以下幾個(gè)方面展開:1.結(jié)合前期施工勘察資料,對(duì)大秦嶺隧道隧址區(qū)地形地貌、地層巖性、地質(zhì)構(gòu)造等工程地質(zhì)條件進(jìn)行分析評(píng)價(jià)。2.著重研究隧址區(qū)區(qū)域水文地質(zhì),諸如地下水賦存和地下水循環(huán)特征等;采用大氣降水入滲法、地下水徑流模數(shù)法及地下水動(dòng)力學(xué)法三種方法對(duì)隧址區(qū)進(jìn)行分段涌水量計(jì)算,并結(jié)合相關(guān)水文地質(zhì)資料對(duì)整條隧道進(jìn)行分段富水特性分析和水文地質(zhì)條件評(píng)價(jià)。3.結(jié)合隧址區(qū)水文地質(zhì)、工程地質(zhì)背景資料,提出采用以水文-工程地質(zhì)分析方法為核心,堅(jiān)持物探手段和地質(zhì)分析相結(jié)合,長(zhǎng)期與短期預(yù)報(bào)相結(jié)合,在隧道超前預(yù)報(bào)工作中合理安排應(yīng)用TSP、GPR和紅外探水三種物探手段,最后結(jié)合隧址區(qū)地質(zhì)條件和掌子面地質(zhì)素描資料來對(duì)超前預(yù)報(bào)工作的準(zhǔn)確性進(jìn)行綜合判定的預(yù)測(cè)方法,并應(yīng)用該預(yù)測(cè)方法指導(dǎo)大秦嶺隧道超前預(yù)報(bào)工作。4.針對(duì)大秦嶺隧道開挖過程中掌子面前方圍巖體破碎和涌突水兩種常見地質(zhì)災(zāi)害建立模糊綜合評(píng)判系統(tǒng)進(jìn)行綜合預(yù)報(bào)分析和研究。大秦嶺隧道隧址區(qū)區(qū)域水文地質(zhì)、工程地質(zhì)條件復(fù)雜。隧道施工過程中穿越斷層地帶較多,斷層附近,巖體破碎;地下水以基巖裂隙水為主,滲入-徑流型循環(huán)系統(tǒng),局部地段巖體富水;開挖過程中,采用上述超前預(yù)報(bào)工作方法成功的構(gòu)建了一套適合該隧道的動(dòng)態(tài)預(yù)測(cè)系統(tǒng),為大秦嶺隧道安全、快速施工提供了技術(shù)支撐和安全保證;模糊綜合評(píng)判系統(tǒng)預(yù)測(cè)結(jié)果與實(shí)際情況基本吻合,也再次證明了該動(dòng)態(tài)探測(cè)系統(tǒng)的適用性和科學(xué)性。
[Abstract]:With the large-scale construction of long, large and deep buried tunnels in the mountainous and heavy hilly areas in the western part of China, the hydrological and engineering geological background across the section in the course of tunnel construction is becoming more and more complicated.In order to ensure the safety and efficiency of tunnel construction, advance geological prediction is extremely necessary.Based on the hydrogeological and engineering geological background data of the Great Qinling Tunnel in Xicheng passenger dedicated Line, this paper analyzes and studies the advance geological forecast of the tunnel.The research focuses on the following aspects: 1.Combined with the previous construction survey data, the engineering geological conditions of the tunnel site area of Dachinling Tunnel, such as topography and geomorphology, stratigraphic lithology, geological structure and so on, are analyzed and evaluated.The regional hydrogeology of the tunnel area, such as groundwater occurrence and groundwater circulation characteristics, is studied emphatically, and three methods, I. E. precipitation infiltration method, groundwater runoff modulus method and groundwater dynamics method, are used to calculate the segmental inflow of water in the tunnel area.Combined with the relevant hydrogeological data, the paper analyzes the water enrichment characteristics of the whole tunnel and evaluates the hydrogeological conditions.Combining with hydrogeology and engineering geological background data in tunnel area, this paper puts forward that the method of hydrology and engineering geology analysis should be taken as the core, the combination of geophysical exploration means and geological analysis, and the combination of long term and short term forecast should be adopted.In the work of tunnel advance prediction, three kinds of geophysical prospecting means, TSPGPR and infrared water prospecting, are reasonably arranged. Finally, combined with the geological conditions of tunnel area and the geological sketch data of the sub-face of the tunnel, the prediction method of synthetically judging the accuracy of the advance forecast work is given.The prediction method is used to guide the advanced forecast of Daqinling tunnel.A fuzzy comprehensive evaluation system is established to forecast and study two kinds of common geological disasters in the excavation process of Daqinling tunnel: rock mass breakage and water inrush in front of the face of the face.The regional hydrogeology in the tunnel site area of the Great Qinling Mountains is complicated with engineering geological conditions.In the course of tunnel construction, there are more cross fault zones, near faults, rock mass is broken; groundwater is dominated by bedrock fissure water, infiltrating into the circulation system of runoff type, local rock mass is rich in water; during excavation,A set of dynamic prediction system suitable for the tunnel is successfully constructed by using the method of advanced forecast, which provides technical support and safety guarantee for the safety and fast construction of the tunnel in the Great Qinling Mountains.The prediction results of the fuzzy comprehensive evaluation system are in good agreement with the actual situation, and the applicability and scientific nature of the dynamic detection system are proved again.
