Study On Safety Construction Technology Of Zhongtiao Mountain Tunnel In Neideng Expressway

With the rapid development of China’s the expressway construction, more and more roadtunnel was constructed, in tunnel construction encountered in the process of all kinds ofcomplicated geological conditions also increases, the geological disasters and accidents occurfrequently, thus causing heavy losses and casualties. To make sure surrounding rock’s stabilityand safety construction engineering design and construction is the top priority of the study.Based on the highway tunnel construction safety control as the breakthrough point,through the numerical simulation based on the finite element theory, the advanced predictionand monitor measuring methods under complex geological conditions of the highway tunnelconstruction safety technology are analyzed, and their adverse geological disaster accidentreason is studied and analyzed, and the corresponding treatment measures to make analysisand evaluation, the thesis mainly research work and results are as follows:1.Through the based on the monitoring and feedback work of the weak broken scheme ofthe tunnel for design and construction of the reasonable scientific and effective analysis andthe stability of the tunnel structure on regression analysis and evaluation.2.In order to ZhongTiao Mountain tunnel disaster accident for the concrete example inshallow buried tunnel collapse section and in front of the tunnel face advanced forecastgeological condition, understand the cause and surrounding rock tunnel collapse to influencescope, for landslide in the measures and treatment plan is to provide effective reference data.3.The finite element analysis software ANSYS in the shallow tunnel collapse period of3-d numerical simulation, the results of numerical simulation were analyzed. Studies haveevaluated the disaster accident of the tunnel of influencing factors, so as to comprehensivelyanalyzes the disaster accident causes and mechanism.4.According to the cause of the disaster accident, and put forward the correspondingtreatment measures, and through the analysis of the process of treatment of site monitoringdata, to the treatment effect of geological disasters made analysis and evaluation.The result of this paper ZhongTiao Mountain for the construction of the tunnel providesthe theory basis for the similar can also be under complex geological conditions of thehighway tunnel construction to provide safe construction experience.
