The Construction Settlement Control Standards And Measures Research Of The Shallow Buried Large Section Tunnel Of Soil Under The Existing Structure

With the development of our country’s economy and technology, The construction andoperation of the highway tunnel has greatly improved, The number of the highway tunnelor the construction speed in our country all rank the first in the world. The development of thetunnel present from short to long, from small to large, from single-function to multipurposemode. To mountain highway tunnel, since the diversity of geological conditions and the limitof the terrain, The form of the tunnel and engineering key problems varies., a series ofnew-type、unique tunnel has appeared, The living examples of beneath the existing buildingsare emerging constantly. This not only presents challenge to engineering design andconstructors, but also offers them great research and practice foundation. previous studiescovered almost every aspect of the tunnel.and the results are fruitful. But as the diversity andcomplexity of the tunnel. The existing researches are still unable to solve a variety ofproblems that appeared in the tunnel. So the research still needs later generations to spare noefforts to explore and have innovation.This article relies on longcheng expressway xihekou tunnel which lies in shanxiprovince. As its Three-lane large section, the depth of the tunnel is shallow, the condition ofthe surrounding rock is bad, passingA heritage under national protection-The Great Wall which is built in Ming Dynasty. UsingANSYS to simulate the actual construction process of the tunnel.Studying the safety of shallow large section of earth tunnel passing existing structure-The Ming Dynasty Great Wall. Focused analysis on how the excavation of the tunnelinfluence the Great Wall. Combining the existing model test and field measurement data tostudy settlement to The Great Wall of structural deformationand the stress conditions.At the same time, to evaluate disposal measures and result ofthe tunnel. Finally, to offer engineering measures and evaluation criteria to ensure the safetyof the tunnel which is large section and the depth is shallow, also, we should keep the safetyof the structure that lies on the tunnel.
