【摘要】：隨著我國交通系統(tǒng)的不斷完善,特別是近幾年大量高速鐵路隧道工程陸續(xù)開工建設,其工程地質(zhì)條件也日趨復雜,過去單純的經(jīng)驗施工和工程類比法已不能滿足現(xiàn)場施工的實際需要,必須通過現(xiàn)場實時監(jiān)測,獲取隧道的圍巖變化規(guī)律,并及時對其進行預處理分析,將分析結(jié)果及時反饋于業(yè)主、設計單位、監(jiān)理及施工單位,以便各單位對隧道變形做出科學預測并優(yōu)化改善隧道設計及其開挖支護方案,以降低施工成本,提高施工速度。本文以牛頭山隧道開挖為工程背景,對信息反饋技術(shù)在隧道施工中的應用進行研究,主要內(nèi)容有:首先,根據(jù)牛頭山隧道實際圍巖情況、施工情況,確定適合牛頭山隧道施工的隧道監(jiān)測方案,并選擇科學合理的監(jiān)測斷面布點方式;其次,實時監(jiān)測各設計監(jiān)測斷面監(jiān)測項目,對監(jiān)測數(shù)據(jù)進行預處理,并建立六種函數(shù)回歸模型,利用origin軟件對預處理結(jié)果通過六種回歸模型進行比較分析,獲得圍巖變形、拱頂收斂及地表沉降規(guī)律函數(shù);最后,對回歸函數(shù)進行求導,獲得圍巖變形、拱頂收斂及地表沉降速率變化函數(shù),繪制變化曲線,對牛頭山隧道開挖方案和支護方案進行優(yōu)化,并通過試驗段對優(yōu)化效果進行了驗證,結(jié)果表明優(yōu)化方案是科學合理的。信息反饋技術(shù)在牛頭山隧道中的成功運用極大降低了牛頭山隧道施工風險,提高了工程質(zhì)量,對其他各類工程施工也具有借鑒意義。
[Abstract]:With the continuous improvement of the transportation system in China, especially the construction of a large number of high-speed railway tunnel projects in recent years, the engineering geological conditions are becoming more and more complex. In the past, the simple experience construction and the engineering analogy method can not meet the actual needs of the field construction. It is necessary to obtain the change law of the surrounding rock of the tunnel through the real time monitoring on the spot, and carry on the preprocessing analysis to it in time. The analysis results are fed back to the owners, design units, supervision and construction units in time, so that each unit can make scientific prediction of tunnel deformation and optimize and improve the tunnel design and excavation support scheme, so as to reduce the construction cost and improve the construction speed. Taking Niutoushan tunnel excavation as the engineering background, this paper studies the application of information feedback technology in tunnel construction. The main contents are as follows: first, according to the actual surrounding rock condition of Niutoushan tunnel, the construction situation, Determine the tunnel monitoring scheme suitable for Niutoushan tunnel construction, and choose a scientific and reasonable monitoring section distribution method; Secondly, the monitoring items of monitoring sections are monitored in real time, the monitoring data are pretreated, and six kinds of function regression models are established. The results of preprocessing are compared and analyzed by six regression models using origin software, and the deformation of surrounding rock is obtained. The law function of arch roof convergence and surface subsidence; Finally, the derivation of the regression function is carried out, and the deformation of surrounding rock, the convergence of arch roof and the change function of surface subsidence rate are obtained, the change curve is drawn, and the excavation scheme and supporting scheme of Niutoushan tunnel are optimized. The results show that the optimization scheme is scientific and reasonable. The successful application of information feedback technology in Niutoushan tunnel has greatly reduced the construction risk of Niutoushan tunnel, improved the engineering quality, and also has reference significance for other kinds of engineering construction.
