Application of Attribute Recognition Theoretical Model on Dam Severity Evaluation

In China, there are thousands of dangerous dams with different deficiencies which are still posing serious threats to downstream public. Facing contradictions between limited resources and large number of dangerous dams to be reinforced, and the need to find out a proper method which can be applied to evaluate the severity of those dams is becoming more and more urgent. Since appraising the severity of dangerous dam is an issue of multi-attributes recognition, a multi-attributes index system based on available dam safety appraisal technology is built, and then Attribute Recognition Theory (ART) is applied to build up an Attribute Recognition Theoretical Model on Dam Severity Evaluation (ARTMDSE) to evaluate the severity of dangerous dams. ARTMDSA is applied on a group of 7 dams and the process and framework of it are introduced. Results of case study show that: first, the method is easy to operate; secondly, evaluation model is available for describing and measuring the severity of every dangerous dam within a group of dams. The results can be taken as technical basis for safety management of a group of dams, especially can be used to determine the sequence of rehabilitation program for dangerous dams.
