Plan On Tunnel Construction Project To Complicated Geologic Tectonic Zone And Measuring Evaluation Of Liner Wall

With the development of national economy and modern communications, the construction of high-grade highways is increasing. Especially in the strategy of West Development, high-grade highways will have to cross the mountains and rolling countries. Because the road was restricted by complex terrain and route indicators, inevitably it need to adopt the tunnel to across the mountains. However, the rapid development of the tunnel project in certain extent lack of coordination to geological exploration, design and development of construction technology, In the construction process may result in the construction of geological disasters, serious impact on tunnel safety and progress. Therefore, how to use existing tools, fast and accurate proved the complex geological structure of geological environment, optimized according to actual situation, and tunnel construction control, quality assessment is another issue of the tunnel construction.Thesis relying on the tunnel project of Dalian Red river, summarizing the methods of geological exploration at home and abroad. Contrary to the actual geological conditions, selecting the means of high-density electrical prospecting form a fast, accurate and effective point. Using the means of geological mapping, water pressure test, pumping test, to conduct a more systematic study of the geological structure along the tunnel of Red river , rock classification, the stress field, dynamic field of water, construction of geological disaster prediction, several key technical problems. Using the software of Phase2D, FLAC/SLOPE2D to take a finite element analysis for slope stability and surface rock stability's affect after the tunnel excavation, and proposing a reasonable program of support and reinforcement. Using LTD-2200 radar to detect the tunnels have been built, evaluating tunnel's construction quality through analyzing radar- detecting images. There have initially be established a technical methodology of tunnel engineering geological survey, design, construction quality evaluation.Geological disaster prediction and forecast of the road tunnels under complicated geologic construction need to be studied deeply from many aspects. Hoping this paper could provide some reference information for the actual construction.
