Anti-slide Pile Monitoring And Evaluation Systembased On The Technology Of Multi-channel Dynamic Test

China is one of the most serious geological disasters countries in the world,especially the slope disease problems. With social and economic development, more and more economic activity launch in the mountains, such as mining, road, dam,construction, etc, which also brings a lot of predominantly landslide geological disasters.Landslide disaster has brought huge impact, not only to China’s economic development,even caused serious damage to people’s lives and property. Therefore, the study of landslide prevention has very important practical significance. Currently the anti-slide pile is widely used as one of the most significant measures for controlling the landslide.Anti-slide pile, however, there are some disadvantages in the design, such as load distribution on pile load uncertainty and uncertainty,at the same time due to the lack of long-term field monitoring of anti-slide pile, which leads to the anti-slide pile design tend to be conservative and waste. For these questions, how to design to give full play to the slip resistance, how to get a comprehensive understanding of the anti-slide pile stress deformation trend, how to forecast and warn the anti-slide pile potential danger,nip in the bud.Aiming at these problems, this thesis, by using Visual Studio.NET multi-functional development platform to build system function framework, combined with SQL Server2005 database function and writing in c# language, preliminary completed anti-slide pile monitoring and evaluation system based on the technology of multi-channel dynamic test. The Thesis main contents as follows:① By reading a amount of relevant literature,System function preliminary could be divided into sensor management system function, monitoring analysis, monitoring and early warning, comprehensive evaluation, and also complete the system interface design.② Establish a multi-channel dynamic acquisition system, realize the real-time dynamic monitoring the working state of the anti-slide pile, such as the change curves of pile top displacement, pile body displacement, earth pressure cell and steel bar stress,etc.③ Establish the anti-slide pile early warning module, the monitoring analysis module, evaluation module. The monitoring analysis, realize the anti-slide pilemonitoring data acquisition, map data list of anti-slide pile monitoring, waveform diagram, histogram, which brings convenience to watch the query. Forecasting warning,in view of anti-slide pile top displacement to choose the appropriate forecasting model to forecast, which is helpful for users to understand the anti-sliding force deformation trend, and can be about the potential risk early warning. Comprehensive evaluation,select the appropriate security and economy evaluation indexes on the security and economy of reasonable judgment, the fuzzy comprehensive evaluation method for comprehensive assessment of landslide protection effect.④ Establish a whole set of anti-slide pile monitoring and evaluation system based on the technology of multi-channel dynamic test. Combined with practical engineering,it can preliminary realize real-time dynamically monitor the working state of the anti-slide pile with nobody, and the potential danger forecasting warning ahead of time and response to avoid further disaster and finally complete the comprehensive evaluation of the slope protection effect, which provides references for the similar landslide treatment.
