为选出最优边坡削坡方案设计,基于层次分析法通过统计、理论分析和数值模拟相结合的方法,研究了边坡削坡方案设计相关的工程实例,并利用求解判断矩阵特征向量的办法,求得指标层因素的权重;对影响边坡削坡方案设计的安全因素进行数值模拟,并对影响边坡削坡方案设计的工程进度和工程造价进行专家评定,从而根据数值模拟和专家评定结果对3种边坡削坡方案设计相对于指标层因素评分,最后比较指标层因素权重与其评分乘积得出最终的评分,评定出最优边坡削坡方案设计。
In order to select the optimal design scheme for slope cutting, based on the analytic hierarchy process (AHP), a combination of statistical analysis, theoretical analysis and numerical simulation are used to study the project examples related to the design of the slope cutting slope. The solution of the matrix eigenvector Method to obtain the weight of the index layer factors; numerical simulation of the safety factors affecting the slope slope program design and expert evaluation of the project progress and project cost that affect the slope slope program design, according to numerical simulation and experts The results of the assessment of the three kinds of slope cutting program design relative to the index layer factor score, and finally the index layer factor weight and its score to get the final product of the rated to assess the optimal slope slope program design.
