【摘要】 分析了声波透射法综合判据中的单一判据结合法、K值综合判据法及多因素模糊综合判据法的基本思路、实施步骤及各自的优缺点。指出了单一判据结合法为定性分析,K值综合判据法初步实现了定量分析,但两者的评判结果均具有明显的"短板"理论色彩。多因素模糊综合判据法通过建立隶属度矩阵和权值矩阵,利用逐层的矩阵计算,解决了上述综合判据法中存在的问题,并且为超大直径基桩和异型基桩的声测评判提供了解决方案。更多还原

【Abstract】 This paper analyzed the basic idea,implementation steps and their respective advantages and disadvantages of single criterion combination method,K value comprehensive criteria method and multifactor fuzzy comprehensive criteria method in comprehensive criteria of ultrasonic transmission method;and pointing out the single criterion combination method is qualitative analysis,and the K value comprehensive criteria method preliminarily realizes the quantitative analysis,but both of their evaluation results have colored with obvious "short board" theory. Multi-factor fuzzy comprehensive criteria method,by establishing the membership matrix and weight matrix,using matrix calculation step by step to solve the problems which existed in the above mentioned comprehensive criteria method,and provided the solution for the acoustic detection evaluation of the large diameter piles and piles of different shapes.更多还原
