Safety Model Comprehensive Judgement Application for Dike Construction Risk Evaluation System Research

Inclusive of the consideration for Solid-Liquid double phase character of dike construction, fuzzy comprehensive judgement system model was set up on the basis of Analytic Hierarchy Process as well as Fuzzy Consistency Theorem. With normal membership of fuzzy function, dike construction safety comprehensive judgement was realized by the help of weighted theorem that had been fabricated in the foregoing contents. With indirect theorem of model discrimination, generalized multi-dimension weighted fuzzy discriminating model was set up on the basis of fuzzy comprehensive evaluation. Furthermore, dike section system safety model discrimination for representative dike section was realized and sensitivity analysis for model system was carried out. The dominant factor over the whole dike system is the safety behaviour of dike body which holds on such roles as withstanding flood invasion, saving the proper living condition for the local citizen, carrying out the necessary safety monitoring on the dike section etc. When considering dike body characteristics as well as the exterior and interior facets over the dike body safety, therefore, the systematic peculiarity is also relevant to the dike body model. With so many quantitative indexes on this model in addition to the ostensive fuzzy behaviour of porous medium([1,2,3]), fuzzy comprehensive judgement system model would be implemented here. In order to practise instant management for the dike structure, for instance, picking out the most consistent section and the most inconsistent with normal section, ascertaining the normally safe dike section, basically safe dike section, partly safe section, unsafe dike section, the comparison between the target sections and normal section which shows the certain work-condition as well as superior safety, has been put into practice according to their various chasms with fuzzy comprehensive judgement and modification theory([4]).
