The invention discloses a method, a
system and a device for quickly matching
underwater defect repair schemes of a reservoir dam, and belongs to the technical field of dam
underwater defect repair. The method comprises the following steps: firstly, based on reservoir dam historical repair cases (including damaged parts,
repair processes, materials, equipment and results), constructing an
underwater repair
evaluation system including a building
system, an external working condition
system, a damage classification system, a repair process system, a
material system and an equipment system, and setting scores for all system elements; establishing an underwater restoration
decision model containing restoration necessity, feasibility and scheme decision, and calculating scores of the three by using an improved
entropy weight method; and when the target dam is damaged, if the necessity and feasibility of model judgment are both met, outputting an optimal repair scheme. The system comprises corresponding function modules, and the device comprises a memory, a processor and a
computer program for realizing the method. According to the method, the optimal scheme can be quickly matched, and the repairing effect and efficiency are improved.
