对土工潜在危险性的综合评判是人们在设计、施工和交付使用后都很关心的问题。当然希望这种综合评判尽可能反映实际情况。决定这种潜在危险性的因素往往较多,如何对诸因素进行综合评判,是一个具有现实意义而且应该优先解决的问题。过去,人们常按照数量化理论进行评分的办法加以评判。本文提出的模糊数学方法是将诸因素对土工潜在危险性的影响程度用隶属函数来表示,然后按照模糊数学原理进行综合评判。相比之下,本文提出的方法具有独到之处,应该引起土木工程师足够的重视。为说明这种方法的特点和实际应用,本文还给出了一个分析滑坡潜在危险性的计算实例。
The comprehensive assessment of potential hazards of geotechnical work is a matter of concern to people after their design, construction, and delivery. Of course, it is hoped that this comprehensive evaluation will reflect the actual situation as much as possible. The factors that determine this potential risk are often many. How to comprehensively evaluate various factors is a question that has realistic significance and should be solved first. In the past, people often judged according to quantification theory. The fuzzy mathematics method proposed in this paper is to express the degree of influence of various factors on the potential danger of the earthwork by the membership function, and then conduct a comprehensive evaluation according to the principle of fuzzy mathematics. In contrast, the method presented in this paper has unique features that should cause civil engineers to pay enough attention. To illustrate the characteristics and practical application of this method, a calculation example for the analysis of potential hazards of landslides is also given.
