【摘要】：我國(guó)交通建設(shè)近些年來(lái)飛速發(fā)展,對(duì)隧道工程建設(shè)的投入隨之加大,可是在隧道施工過(guò)程中,地質(zhì)狀況復(fù)雜多變,在隧道開(kāi)挖過(guò)程中會(huì)引發(fā)多種地質(zhì)災(zāi)害,這些具有隱蔽性、復(fù)雜性和突發(fā)性,各種不良地質(zhì)災(zāi)害會(huì)導(dǎo)致很多工程事故的發(fā)生。通過(guò)對(duì)隧道監(jiān)控量測(cè)和超前地質(zhì)預(yù)報(bào)文獻(xiàn)資料的研究,本文簡(jiǎn)要介紹了隧道監(jiān)控量測(cè)中的必測(cè)項(xiàng)目和選測(cè)項(xiàng)目的數(shù)據(jù)采集所需的設(shè)備及方法,并且對(duì)目前隧道超前地質(zhì)預(yù)報(bào)的一些方法進(jìn)行了介紹。本文以莊河隧道第三方監(jiān)控量測(cè)項(xiàng)目為依托,在莊河隧道的施工過(guò)程中實(shí)施了監(jiān)控量測(cè),進(jìn)行了必測(cè)項(xiàng)目中的拱頂下沉量測(cè)、凈空收斂量測(cè)及淺埋地表沉降量測(cè)。選取莊河隧道左線ZK1+120斷面對(duì)量測(cè)數(shù)據(jù)使用EXCEL進(jìn)行回歸分析,得出相應(yīng)的回歸曲線,并且用此回歸曲線對(duì)該隧道同類圍巖開(kāi)挖后的穩(wěn)定時(shí)間和最終位移值進(jìn)行預(yù)測(cè),確定二次襯砌施作的時(shí)間,更好地指導(dǎo)隧道能夠安全施工。本文較為詳細(xì)的介紹了TST法和MALA地質(zhì)雷達(dá)法超前地質(zhì)預(yù)報(bào)的原理、數(shù)據(jù)的采集、數(shù)據(jù)的處理以及在莊河隧道超前地質(zhì)預(yù)報(bào)工作中的應(yīng)用。TST法對(duì)軟弱構(gòu)造帶、斷層、溶洞、破碎帶等不良地質(zhì)體的預(yù)報(bào)效果較好；MALA地質(zhì)雷達(dá)法對(duì)地質(zhì)體的介電常數(shù)、電導(dǎo)率的差異反映敏感,能夠較為準(zhǔn)確的探測(cè)和預(yù)報(bào)前方圍巖的富水區(qū)段和破碎圍巖的位置。莊河隧道超前地質(zhì)預(yù)報(bào)采用了長(zhǎng)距離(TST法)與短距離(MALA地質(zhì)雷達(dá)法)預(yù)報(bào)方法相結(jié)合的方式,利用超前地質(zhì)預(yù)報(bào)數(shù)據(jù)處理后得出的結(jié)果與隧道實(shí)際開(kāi)挖結(jié)果進(jìn)行對(duì)比,在隧道施工過(guò)程中超前地質(zhì)預(yù)報(bào)的結(jié)果與實(shí)際開(kāi)挖的結(jié)果基本一致,并且為隧道左線ZK1+195-ZK1+240的地勘資料做了補(bǔ)充。通過(guò)超前預(yù)報(bào)得到了莊河隧道圍巖的完整性、節(jié)理裂隙發(fā)育程度及含水層等典型不良地質(zhì)的響應(yīng)特征,進(jìn)而提高了莊河隧道施工后期的超前地質(zhì)預(yù)報(bào)工作的準(zhǔn)確率,為施工方提前采取相應(yīng)支護(hù)措施提供了準(zhǔn)確的依據(jù),確保了莊河隧道的施工安全,為以后其他類似項(xiàng)目提供了一定的參考價(jià)值。
[Abstract]:With the rapid development of traffic construction in China in recent years, the investment in tunnel construction has increased, but in the process of tunnel construction, the geological conditions are complex and changeable, which will lead to a variety of geological disasters in the process of tunnel excavation, which have concealment, complexity and sudden, and all kinds of bad geological disasters will lead to the occurrence of many engineering accidents. Based on the study of tunnel monitoring measurement and advanced geological prediction literature, this paper briefly introduces the equipment and methods needed for data acquisition of necessary and selected items in tunnel monitoring and measurement, and introduces some methods of tunnel advanced geological prediction at present. In this paper, based on the third party monitoring and measurement project of Zhuanghe Tunnel, the monitoring and measurement are carried out in the construction process of Zhuanghe Tunnel, and the arch roof subsidence measurement, clearance space convergence measurement and shallow buried surface settlement measurement in the required project are carried out. The ZK1 120 measurement data of the left line of Zhuanghe Tunnel are selected for regression analysis with EXCEL, and the corresponding regression curve is obtained, and the stability time and final displacement value of the same kind of surrounding rock of the tunnel are predicted by this regression curve, and the time of secondary lining is determined, which can better guide the safe construction of the tunnel. This paper introduces in detail the principle of TST method and MALA geological radar method in advance geological prediction, data collection, data processing and its application in advance geological prediction of Zhuanghe Tunnel. TST method has good prediction effect on weak structural zone, fault, caverns, broken zone and other bad geological bodies. MALA geological radar method is sensitive to the difference of dielectric constant and conductivity of geological bodies, and can accurately detect and predict the location of rich water area and broken surrounding rock in front of the surrounding rock. The advance geological prediction of Zhuanghe tunnel adopts the combination of long distance (TST method) and short distance (MALA geological radar method) prediction method. The results obtained from advanced geological prediction data processing are compared with the actual excavation results. The results of advanced geological prediction in the process of tunnel construction are basically consistent with the actual excavation results, and the geological prospecting data of ZK1 195-ZK1 240 on the left line of the tunnel are supplemented. The integrity of surrounding rock, the degree of joint fracture development and the response characteristics of typical bad geology, such as aquifer, are obtained by advanced prediction, which improves the accuracy of advanced geological prediction in the later stage of Zhuanghe tunnel construction, provides an accurate basis for the construction of Zhuanhe tunnel in advance, ensures the construction safety of Zhuanghe tunnel, and provides certain reference value for other similar projects in the future.
