Development And Its Application Of The Monitoring Information Managemment & Data Analysis Network System For Rock Mass Slope

For the safety and stabilization of slope engineering in complex rock masses, safety monitoring should be implemented at construction and operation periods in order to ensure the immediate feedback of slope deformation, supporting stress, seepage pressure and attaining the expected purpose of optimaling design scheme and guaranteeing stability of slope.In order to change the backward situation of management and analysis of safety monitoring data of the slope, we develop the monitoring data management and analysis system for rock mass slope by using VC++ and SQL Server 2000. This system can improve efficiency and correctness of monitoring information arrangement analysis and has enormous economic benefits in guaranteeing stability of slope and fully developping their actions.The main aspects of the dissertation are as follows:(1) The original observation data of slope safety monitoring should be preprocessed before reorganizing and analyzing. Firstly, studying on the processing method of original observation data, including reliability inspection of monitoring data, error identification and analysis, interpolating and smoothing of monitoring data, etc.(2) The deformation forecasting is a common means of the analysis of stability of slopes. On the Basis of analyzing influence factors of rock mass slope deformation, we establish a statistical regression analysis model for rock mass slope deformation taking into account the influence of aging, temperature and rainfall. Then, this model was added to the monitoring data management and analysis system with stepwise regression algorithm. Computed results of project example show that the model has a ideal result that the interrelational coefficient of regression is high and residual standard deviation is low.(3) Taking the relating database, SQL Server 2000, as the background server database and the programe developed by Visual C++ as the client system, we develop the monitoring data management and analysis system for rock mass slope with C/S architecture. The system has the advantages of advancement, reliability, generality and extension. This paper go into particulars of developing process of the system, including general design idea of the system, database and front-head software design and development.(4) The system is applied to Longtan and jingping stage- I Hydroelectric slope project. The remote real-time sharing and network management and analysis for monitoring information and monitoring data of the slope have been realized. Monitoring analysis results feedback to designers timely, which plays an important role in evading design and construction risk and ensuring the construction and operation safety of the slope.
