【摘要】 本文运用模糊数学方法,研究基坑工程围护方案的评审方法,以及基坑工程围护方案的优选方法,并结合具体的基坑工程评审内容,说明该方法具体的应用步骤。该方法中,根据专家评分结果确定各评审项目的权重,再根据模糊综合评判法和最大隶属度原则建立基坑围护方案的评价矩阵,最后将不同围护方案的评价矩阵量用相同的量化矩阵量化,以实现基坑方案的评价和不同方案的优选。更多还原

【Abstract】 Evaluation method for foundation pit engineering was researched using fuzzy mathematical method in this thesis.The retaining wall scheme of foundation pit can be evaluated by this method,also the optimization among different schemes was easily achieved with this method.The application steps of the method for specific evaluation contents were explained in detail.Firstly,the weights of evaluation items were calculated based on expert grading,then evaluation matrix was calculated using fuzzy comprehensive evaluation method and maximum membership degree law.Finally,the scheme optimization was determined by the values of different evaluation matrixes which were quantized by the same quantization matrix.更多还原
