| Abstract: | In order to solve the problem that conflicts may exist among multi-source monitoring information,a new fusion evaluation model for conflict evidence of multi-effect quantity in high arch dams is established by using the discount coefficient method of D-S evidence theory which can highlight the role of key evidence and weaken the influences of conflict evidence.An engineering example is given.The proposed model can reasonably and effectively weaken the negative influences of the conflict monitoring information on the comprehensive safety evaluation of the high arch dams. |
| Keywords: | high arch dam multi-effect quantity D-S evidence theory discount coefficient comprehensive evaluation |
