Research On Xi’an Metro Tunnel Automatic Monitoring And Deformation Data Analysis

The subway plays a significant role in relieving urban traffic pressure,at present many big cities in our country have the subway,or in the process of building. The subway traffic construction has become an important project in infrastructure of China.In Subway tunnel construction or operation of the process, a number of factors such as geological conditions, groundwater, surface buildings developing and tunnels their load capacity, will have an impact on the tunnel structure to make it happen settlement, offset. deformation. For those serious distortion or deformation monitoring demanding lot, if it cannot be automated, continuous, long-term deformation monitoring, it is difficult to detect danger, will pose a serious threat to tunnel safety. In particular, this ground fissures, loess, more the ancient building in Xi’an actual situation subway monitor becomes particularly important. There are many ways in Subway tunnel real-time deformation monitoring and automation, this paper takes advantage of measuring robotic automation, intelligent features to monitor subway tunnel automatic deformation studies. Based on measurements of the robot automatic deformation monitoring has become an important measure to protect the safety of the subway tunnel, with strong theoretical and practical significance. It is the purpose of this study. Specific studies are as follows:(1) Study to establish a unified coordinate baseline tunnel method, according to the environmental characteristics of the subway tunnel atmosphere proposed Free Station determine the coordinates of the corners of the intersection point of the work.(2) After the introduction of a combination of prescription poor test, from the perspective of statistical theory to analyze the stability of the subway tunnel deformation monitoring network of reference, and analyzes its accuracy.(3) On the deformation monitoring data processing and analysis, reflecting the tunnel local and overall deformation.(4) Based on Topcon measuring robot MS05 AXII subway tunnel construction process for automatic deformation monitoring techniques have been studied to achieve an online automatic deformation monitoring robot control measure function.Subway tunnel engineering monitoring instance shows that this study realizes the measurement of robot automatic monitoring data, intelligent processing errors that appear in the acquisition, remote monitoring data transmission, automatic data storage acquisition, processing, output measurement results, and other diverse functions, to achieve the desired goal.
