The Research Of Vertical Subgrade Settlement And Tilt Measurement System

With the rapid development of rail construction, security has been more attention. However, in the works as well as completed, foundation settlement are difficult to avoid. In order to grasp the size and variation of Settlement, Settlement detection is essential. Therefore, to enhance the real-time monitoring of embankment settlement, improve accuracy, the work has become an important railway work.Subject of this paper, the national 863 Program "subgrade settlement comprehensive real-time monitoring techniques" (2007AA11Z122), focus on vertical settlement of subgrade real-time monitoring of sub-topics, in the analysis of the current Settlement of the basis of the technical characteristics of proposed simultaneous measurement of vertical subgrade settlement and tilt of the design ideas in detail the components of the system, set up to locate sensing, laser ranging, angle sensor, infrared communication, wireless transmission for the main modules of the test platform for the completion of the laboratory After debugging, field alignment, and debug system according to the site environment to ensure system reliability and accuracy, and effective to ensure the vertical subgrade settlement and tilt of real-time monitoring.
