基于数据包络分析方法的爆破方案效应评估

根据影响爆破地震效应的主要内在和外在因素,利用数据包络分析方法,建立爆破方案效应评估模型。该模型运用重要性排序方法确定各个输入和输出指标的权重,利用C2R模型对爆破方案的有效性进行评估,寻找出最优爆破方案。该方法与工程实际应用相结合,简单实用、易于编程、显示出较好的可靠性。

Based on the data envelopment analysis method,with the main internal and external divisors of the blasting load,we establish the model of the assessment of effects of blasting scheme.We determine the weights of each input and output index taking advantage of importance ranking method,assess of effects of each blasting scheme according to C2R model,and find out the optimal blasting scheme according to results of evaluation.The method combining with the practical application of engineering is simple,practical,easy to program,so it shows good reliability.
