【摘要】：在中國交通事業(yè)高速發(fā)展時(shí)期,隧道作為跨山越嶺的一種主要結(jié)構(gòu)在交通系統(tǒng)中承擔(dān)著主要作用。但是在這些已建成的隧道中,由于隧道工程設(shè)計(jì)和施工的不當(dāng)會出現(xiàn)各種各樣的問題,有不少隧道存在各種各樣的嚴(yán)重缺陷。目前這些缺陷隧道威脅著人們的生命和財(cái)產(chǎn)安全。在最近幾年中,媒體也報(bào)道了一些,例如上海地鐵四號線過江隧道發(fā)生隧道滲水事故,原因是隧道邊部存在隱伏斷層和溶洞破壞了隧道的防水系統(tǒng)。因此,工程的檢測質(zhì)量得到了社會各方的重視�？茖W(xué)技術(shù)的高速發(fā)展帶動了檢測儀器和檢測手段的不但更新。地質(zhì)雷達(dá)法是無損的、效率高、分辨率高,快速采集雷達(dá)圖像等優(yōu)勢,能夠準(zhǔn)確定位出缺陷的位置,并對及時(shí)對隱患進(jìn)行處理,為我國的交通建設(shè)帶來了雄厚的技術(shù)支持。本文首先介紹地質(zhì)雷達(dá)的工作原理以及其在隧道檢測過程中相關(guān)參數(shù)的設(shè)定。然后說明了現(xiàn)場檢測工作開始前所要做的準(zhǔn)備,包括:現(xiàn)場的檢測條件、臺車的搭建、雷達(dá)天線的選擇和參數(shù)的選擇及標(biāo)定,還有一些相關(guān)的操作要點(diǎn)和應(yīng)急防范措施。論文重點(diǎn)部分是通過地質(zhì)雷達(dá)在現(xiàn)場相關(guān)檢測項(xiàng)目中采集回來的一些實(shí)例圖像,講述在隧道施工過程當(dāng)中常見的脫空、欠密實(shí)、欠厚和鋼筋缺失等一些缺陷及病害。同時(shí)在大量數(shù)據(jù)資料的收集過程中,通過總結(jié)找到了一些對雷達(dá)數(shù)據(jù)產(chǎn)生干擾的干擾源及其所產(chǎn)生的干擾圖像,也對今后的工作有很大的幫助,使我們更夠更準(zhǔn)確的進(jìn)行判識。最后簡要的介紹卡斯特地貌地區(qū)巖溶探測工作。在鐵路高速發(fā)展的今天,尤其是我們西南高原地區(qū)鐵路的不斷增多,而且其地質(zhì)情況復(fù)雜,鐵路線路又多是穿山而過,線路中以隧道居多。地質(zhì)雷達(dá)法作為現(xiàn)場對隧道質(zhì)量的監(jiān)控最普遍的方法,我們也通過大量的現(xiàn)場檢測及資料分析找到了許多辨別偽缺陷和真缺陷的方法,是我們能夠快速準(zhǔn)確的辨識出缺陷類型及區(qū)域,有助于下一步施工單位對缺陷的處理,提高實(shí)體工程的施工質(zhì)量,同時(shí)對保障最后鐵路的運(yùn)營通車安全具有重大的意義。
[Abstract]:In the period of rapid development of China's transportation industry, tunnel, as a main structure across mountains and mountains, plays a major role in the transportation system. However, in these built tunnels, many tunnels have various serious defects due to various problems arising from the improper design and construction of tunnel engineering. At present, these defective tunnels threaten the safety of people's lives and property. In recent years, the media have also reported some cases, such as the tunnel seepage accident occurred in the tunnel of Shanghai Metro Line 4, because of the hidden faults along the tunnel side and the waterproofing system of the tunnel destroyed by the karst cave. Therefore, the quality of engineering detection has been paid attention to by all parties in the society. With the rapid development of science and technology, the testing instruments and means are not only updated. The geological radar method is nondestructive, efficient, high resolution, fast acquisition of radar images and other advantages, can accurately locate the location of defects, and timely processing of hidden dangers, for our country's traffic construction has brought strong technical support. This paper first introduces the working principle of GPR and the setting of relevant parameters in tunnel detection. Then it explains the preparation to be made before the field detection work starts, including: the detection condition on the spot, the construction of the station car, the selection of radar antenna and the selection and calibration of the parameters, and some relevant operation points and emergency preventive measures. The key part of this paper is to describe some defects and diseases in the tunnel construction process, such as void, underdensity, underthickness and lack of steel bar, through some case images collected by GPR in the field related detection project. At the same time, in the process of collecting a large amount of data, we find some jamming sources and their jamming images by summing up the radar data, which will be of great help to the future work, so that we can more accurately identify. Finally, the karst exploration in Karst geomorphology area is briefly introduced. With the rapid development of railway, especially in the southwest plateau of our country, the railway is increasing, and its geological condition is complicated, the railway line is mostly through the mountain, and the tunnel is the most of the railway lines. As the most common method for monitoring the quality of tunnels in the field, we have also found many methods to identify false and true defects through a large number of on-site detection and data analysis. Is that we can quickly and accurately identify the types and areas of defects, which is helpful to the next step of the construction units to deal with defects, improve the construction quality of solid projects, and at the same time to ensure the safety of the final railway operation has great significance.
