Rsearchment On High Slope Monitoring Methods Of The "3052" Project In Hegang City

In recent years, mining, water conservancy, transportation and construction engineeringin our country vigorous development, the formation of the mine slope and dam abutmentslope, the reservoir bank slope road, rail and road slope, etc. The size, number, as well as thecomplicated environment, the complexity of geological conditions are all unprecedented. Athome and abroad a large number of geotechnical slope instability or sliding shoe see not fresh,to the national construction and people’s life and property security caused serious loss anddamage, has become a global geological disasters. Therefore, to establish scientific andrational high slope monitoring, early warning mechanism is particularly important. In thispaper, the author on the basis of comprehensive analysis of the traditional monitoringmethods, according to actual participation in high slope monitoring project, study on highslope monitoring programme. Including the choice of benchmark network coordinate system,the benchmark net shape selection and layout, benchmark stability analysis method, etc.; Inaddition, this article synthetically monitoring net shape selection and layout, the selection ofmonitoring network monitoring method, the processing of monitoring data analysis and themethods of improving the quality of the observation that; Finally, put forward to GPS faststatic monitoring method, the high precision level measurement and the combination of deephorizontal displacement of soil slope monitoring plan, the monitoring scheme is verified inthe actual implementation of the feasibility, reliability, and the scientific nature. Summarizingpractical experience, to the actual problems in the process of engineering, scientific solutionsand reasonable suggestions, in order to help readers engaged in related work.(1) the high slope monitoring datum net of monitoring solution. Considering thereliability of the benchmark network, datum net shape choice triangle net; This benchmarknetwork coordinate system selection method, ensure high precision of the monitoringnetwork, and can be used as a benchmark factory other measurements; In this paper, thehorizontal reference node and the stability of the height datum network analysis method cancheck place to benchmark the unstable points in the net, for monitoring network observationanalysis, provide a reliable guarantee. (2) the study of high slope monitoring network design. Rapid static positioning way canmeet the requirements of users and high precision, high reliability, high efficiency;Considering the double base station to higher efficiency and better reliability, in combinationwith the project arranged by the personnel, instrument, used in high slope monitoringnetwork monitoring network USES the method of double base station.(3) horizontal displacement monitoring data, this paper introduces the verticaldisplacement monitoring data and the analysis of survey data processing method, namely theapplication rate of change of displacement monitoring points and the cumulativedisplacement variation, reflect the instantaneous state of high slope; This article lists in theobservation process and factors affected the accuracy of data acquisition in the process ofdata processing, and based on personal experience the discriminant method and reasonableSuggestions are given.(4) with the author’s participation in high slope monitoring project, based on the highslope monitoring successfully predict slope showed signs of landslides in the process of caseanalysis, verified the high slope monitoring datum network is stable, monitoring datacollection method and the analysis method is reasonable, thus confirms the project of highslope monitoring scheme adopted by the feasibility, reliability and validity.
