Study On The Theory And Method Of Health Diagnose For Earth-Rockfill Dam

The theory and method of health diagnose for earth-rockfill dam are hot issues in the research domain of dam safety monitoring. By means of the theories of mathematics and mechanics together with the features of earth-rockfill dam, theory and method of health diagnose for earth-rockfill dam are studied. The primary contents as follows:(1) The concepts of the health diagnose item and value of health diagnose of earth-rockfill dam are presented. The guidelines of health diagnose of earth-rockfill dam and the quantization methods for original diagnose information of bottom diagnose items are analyzed. The diagnose health value formulas derived from the methods are deuced, and corresponding analysis programs are developed.(2) Two determination methods of importance relocation between diagnose items are analyzed in this dissertation, namely the analytic hierarchy process method(classed as complete judgment matrix and imperfect judgment matrix) and fuzzy consistent judgment matrix method, respectively. Based on the methods, fusion method of determination of importance relocation is established. Furthermore, adjustable importance method according to the variation of health value is analyzed.(3) On the base of researches on selective principles and selective method for health diagnose items, the structure system of health diagnose items is established. Combined with the health diagnose model, the comprehensive analysis method of health diagnose is presented.(4) The structure system of health diagnose items used for comprehensive health diagnose of Maojianshan earth-rockfill dam is established. The original diagnostic information is quantified by use of the quantization theory and method for single health diagnose item. In addition, the results of every item's importance are obtained according to the determination methods of importance relocation between diagnose items. Based on the analyses given above, the dam's health situation is diagnosed by the application of the comprehensive analysis theory and method of health diagnose for earth-rockfill dam...
