Technical Research Of Comprehensive Safety Evaluation System On Qipanshan Reservoir Dam

Dam is the primary hydraulic construction of reservoir, and to improve and heighten dam's safety actuality in our country has become to be the great event, which is connected to the national economy and the people's livelihood. According to investigating earth-rockfill dam's safety evaluation technology at home and abroad, the comprehensive evaluation technology based on fuzzy comprehensive method,gray associated degree analysis and NN method are analyzied, and the application of these methods are practiced in qipanshan reservoir dam's safety comprehensive evaluation.The main content of the research is: The research actuality of multi-arrangement comprehensive evaluation technology are obtained at home and abroad, the technology and discuss the model and method for comprehensive evaluation are constrast; Based on fuzzy comprehensive method,gray associated degree analysis and NN method, impolder the program model which has current interface; Take the large or medium-sized dam for example, research and ensure the index system,scale and evaluation rule of monomial index, and constitute analyzing evaluation repository of the dam; The comprehensive analyzing program of earth-rockfill dam are applied to analyze the safety actuality of Qipanshan reservoir.The characteristic of the research is:(1) Earth-rockfill dam's index system and evaluation rule are analyzed , the assured system is a all-around,layered system and also easy to be evaluated and handled.(2) Develop earth-rockfill dam safety evaluation software by using computer software, with this system people can analyze different earth-rockfill dam's safety actuality. The system support the construction of index system,the calculation of scale and the safety comprehensive evaluation.The exploitation result are applied in Qipanshan reservoir in Liaoning province,and the applying effect is good. The system can combine with the earth-rockfill dam automatic monitoring system. Combining with the earth-rockfill dam safety analyzing system, the research can exert applying benefit, and it has good extended foreground.
