【摘要】：在隧道施工過程中,監(jiān)控量測具有確保安全,指導施工、反饋信息、修正設計、積累資料的重要作用,因此不可缺少。本文建立在對夏村隧道進行監(jiān)控量測的基礎之上,通過監(jiān)控量測,能夠觀測到監(jiān)控斷面的變形量大小,可以預測到檢測斷面的最終變形量以及二襯施做的合理時機,并且通過使用黃金分割,應用相關軟件,找到了滿足實際變形值的隧道圍巖參數(shù)。這些等效的圍巖參數(shù)值要比室內(nèi)實驗獲得的參數(shù)值有更大的實際工程應用價值。本文主要內(nèi)容包括:1)對三柳高速夏村隧道的工程背景、工程條件進行調(diào)研和分析。2)根據(jù)規(guī)范并結合實際現(xiàn)場情況,制定出監(jiān)控量測的工作方案,并嚴格按照該方案執(zhí)行監(jiān)控量測工作,將每天的檢測結果進行匯總和整理,向施工單位定期提交檢測報告。3)利用實際得到的檢測數(shù)據(jù),分別根據(jù)指數(shù)函數(shù)、雙曲函數(shù)、對數(shù)函數(shù)對它們進行回歸分析,找出吻合度最高的一種函數(shù),然后通過回歸函數(shù)預測該斷面的最終變形以及二襯施做的合理時機。4)以ZK5+760斷面的變形數(shù)據(jù)為依據(jù),建立模型,進行位移反演分析,得到了與實際變形情況相符合情況下的等效圍巖參數(shù),以此參數(shù)為依據(jù),利用FLAC3D數(shù)值模擬,可以為接下來隧道的施工以及設計提供必要的依據(jù)。本文利用了夏村隧道圍巖變形的監(jiān)控量測的數(shù)據(jù),完成了變形回歸分析工作,這樣能使得監(jiān)控量測工作所得到的實際數(shù)據(jù)更好地為隧道的現(xiàn)場施工服務。利用夏村隧道的實測數(shù)據(jù),完成了圍巖參數(shù)位移反演分析,這為夏村隧道的等效參數(shù)獲取提供了一種更加省時、經(jīng)濟的方法,當遇到相似情況時,可以以此為一定的借鑒,同時對隧道工程領域中反分析法的使用有借鑒之意義。
[Abstract]:In the process of tunnel construction, monitoring and measurement plays an important role in ensuring safety, guiding construction, feedback information, modifying design and accumulating data, so it is indispensable. Based on the monitoring measurement of Xiacun tunnel, the deformation of the monitoring section can be observed, the final deformation of the monitoring section can be predicted and the reasonable time for the second line application can be predicted. Through the use of golden section and relevant software, the parameters of tunnel surrounding rock that meet the actual deformation value are found. These equivalent values of surrounding rock parameters have more practical application value than those obtained by indoor experiments. The main contents of this paper include: (1) investigation and analysis of the engineering background and engineering conditions of Sanliu Expressway Xia Village Tunnel. (2) according to the specifications and combined with the actual situation of the site, the work plan of monitoring and measuring is worked out. And strictly according to the program to carry out the monitoring and measurement work, the daily test results will be summarized and arranged, regularly submitted to the construction unit testing report .3) using the actual test data, respectively according to the exponential function, hyperbolic function, The logarithmic function makes regression analysis on them, finds out one of the functions with the highest degree of coincidence, and then predicts the final deformation of the section by regression function and the reasonable time. 4) based on the deformation data of ZK5 760 section, the model is established. The equivalent surrounding rock parameters in accordance with the actual deformation are obtained by the displacement inversion analysis. Based on these parameters and the FLAC3D numerical simulation, the necessary basis for the construction and design of the following tunnel can be provided. This paper makes use of the monitoring data of the surrounding rock deformation of Xicun Tunnel and completes the work of deformation regression analysis, which can make the actual data obtained from the monitoring and measuring work better serve for the construction of the tunnel. Based on the measured data of Xiacun tunnel, the displacement inversion analysis of surrounding rock parameters is completed, which provides a more time-saving and economical method for obtaining equivalent parameters of Xiacun tunnel. At the same time, it can be used for reference in the field of tunnel engineering.
