Complex Monitoring Of Slope Of High Speed Railway Studies On Information Management And Evaluation Of Slope Stability

In order to ensure the security and stability of complex rock slope, it was significant for the slope engineering to be monitored carefully in the process of the construction and operation.Then designers could grasp timely a series of monitoring information in slope deformation, seepage, seepage pressure, support stress and so on and maked the design of the appropriate adjustment and optimization.Today,monitoring governance integration was very advanced geotechnical engineering way because monitoring data could not only reflect the dynamic status quo of the slope, but also predicted the slope of the development trends and captured the precursor to largescale landslide in time. Therefore monitoring data collection and analysis was extremely essential in slope stability and security of running.This paper relied on the Changsha-Kunming railway passenger dedicated line, to a mountainous area passenger dedicated line of high and steep rock slope monitoring, monitoring data processing, analysis on stability of high and steep slope, complex structure on the informatization construction control research.1. Investigated the slope monitoring program of the deformation, it was form the information monitoring role, a complete introduction of the monitoring program, slope stability, security, comprehensive evaluation and alarm value had conducted in-depth study of the Changsha-Kunming line slope stabilityof the vigilance of the safety factor value; slope monitoring alarm needed to the design, experience, and the changes of slope monitoring environment of the scene that valued to determine.2. In order to monitor data cuold be conveniently by the engineering and technical personnel to use, based on the programming language Visual Basic, database Excel, and with the help of open database connectivity (ODBC) technology to achieve access to the database, the development of high speed railway slope monitoring visualization information query and analysis system, realized the monitoring data storage management, graphical display, timely prediction, timely feedback, consistented with the dynamic design and visualization of modern design requirements, thus for the slope stability analysised of construction and provided a scientific basis.3.The studied of changsha-Kunming Railway Passenger Dedicated Line DK167+304.371slope considering construction process stability and deformation characteristics. Calculate the potential sliding surface is a circular arc and line (including plane) two kinds of circumstances, and without considering the groundwater and considering the rock and soil are all water saturation of the slope safety coefficient; analysis of the slope in each construction stage, explosion, earthquake effects of slope safety coefficien and the effect on slope t. Finite element method is used to calculate the different stages of construction, without considering the groundwater and consider all is water saturated soil under the conditions of the horizontal and vertical displacement of slope change values, and the slope deformation characteristics were evaluated.
