The Research Of Earth And Rockfill Dam Engineering Emergency Earthquake Damage Assessment

China is located in the Eurasian plate, and the western region is affected by the IndianOcean plate and Eurasian plate while the eastern region is inserted and pushed by thePacific plate. Therefore China had been suffered from frequent earthquake activities andserious earthquake disasters, and is one of the most serious countries suffering fromearthquake in the world. There was6times earthquake which killed more than200,000people and China accounted for4times in the human history. From1949to2000，Variousnatural disasters caused deaths of our country about550,000people，and the earthquakecaused more than1/2death among them. As a consequence, earthquake situation grim andserious earthquake damage is the basic national conditions in our country.At present, the number of dams in China is more than86000and95%of them areearth-rock dams. Earth-rock dams are hazard-affected body in earthquake disasters. On theone hand, the earthquakes cause the destruction of earth-rock dams, which cause directeconomic loss. On the other hand, the earth-rock dams may evolve into risk defending andsecondary flood may cause huge economic losses and casualties, meanwhile the dam can’tplay to the functions of water conservancy facilities normally which cause production andliving difficulties. After the earthquake, through the ease and shortcut evaluation for theloss of earth-rock dams’ disaster, we can carry out the earthquake emergency work validly,distribute relief workers and materials rationally and quickly to get the timely help to avoidthe occurrence of secondary disasters. Meanwhile, through the research of prediction andrapid assessment of the earthquake damage of earth-rock dams, we can deepen theunderstanding of the seismic response mechanism foe earth-rock dams and is able toadopting seismic means before construction and design of dams to avid or lighten thelosses. At present, the research of prediction and rapid assessment for the earthquakedamage of earth-rock dams are scarcely ever at home and abroad. In the face of the severeearthquake situation in our country, this article carries on research on the assessment ofemergency earthquake damage, and can provide theoretical foundation for hydraulicengineering.In this article, the multidimensional rapid evaluation system of earth-rock dams’seismic damage is organized firstly. The system is divided into two aspects. On the onehand, we made the entire content evaluation of the existing earth-rock dams and detailedcombing the "Reservoir Dam Safety Evaluation Method" revised in2003and “Reservoirdam safety evaluation" issued in2000, and secondary grouping the evaluation content.Meanwhile, we bring the grouping result as the interlayer of evaluation system in thisarticle to make the evaluation system of general effect. On the other hand, we carried onrelevance analysis of the indicators for earth-rock dams through the existing seismic dates,seismic damage dates and dam failure experiences to set up the index system of this document. Secondly, we summarized the typical domestic and foreign emergency ratingclassification ideas and combined marine hydraulic engineering characteristics todetermine the dam earthquake disaster classification and grading response. Finally,according to the above summarizes and induces of the earth-rock dam seismic emergencyevaluation system and based on the foundation of fuzzy multiple attribute decision making,the dynamic fuzzy classification method was put forward and tested at some point inYunnan simao earthquake disaster emergency on January26,2005.In this paper, on the basis of summarizing the existing earth-rock dams’ safetyinformation, the earth-rock dams’ safety evaluation was regrouping. Through the analysisof seismic effects of earth-rock dams, earthquake emergency of earth-rock dams’ safetyevaluation system were been set up. Also, a typical emergency state classification methodwas been summarized and for earth-rock dam earthquake emergency safety assessment forgrading. In earthquake emergency of earth-rock dams’ safety evaluation system andgrading state, on the basis of exploratory earth-rock dam engineering geological disasterevaluation and dynamic fuzzy classification model was been put forward.
