基于AHP-Fuzzy法的水下爆破设计方案优选

Design Optimization of Underwater Blasting Based on AHP-Fuzzy Method

针对水下爆破设计参数的多样性及影响因素的复杂性,结合层次分析法(AHP)和模糊数学(Fuzzy)综合评价方法,建立水下爆破设计方案优选模型。权重计算可以反映各个准则及指标对目标的影响程度,为克服权重赋值过程的主观性,该模型采用判断矩阵对权值进行分配。将该模型运用于嘉陵江航道整治三期工程的爆破设计优选,经计算方案1#为最优方案。采用方案1#进行爆破施工,爆区临近桥梁的振速得到很好的控制,岩碴块度达到要求,清碴效果良好。

Because of the diversity of design parameters in underwater blasting and the complexity of influencing factors, the method of analytic hierarchy process （AHP） and Fuzzy comprehensive evaluation were combined to optimize the design model of underwater blasting. Weighting can reflect the influence of various criteria and indicators for the target. In order to overcome the subjectivity of weight assignment process, the judgment matrix was used in the model to make weight distribution. The model was applied to optimize the blasting designs in the third phase of Jialing River waterway regulation engineering, and calculated scheme 1 # was selected as the optimal solution. In blasting construction undertaken with this scheme, the vibration velocity near the critical zone of the bridge was well controlled. Rock has met the requirement of the degree of clinker and slag removal effect is good.
