摘要:
既有铁路隧道衬砌裂损维修方案的合理选择,受到投资成本、自然环境和施工难易程度等因素的影响.针对这些因素,笔者利用可辨识矩阵启发式约简算法、专家评判法和多层次灰色综合评判法综合建立既有铁路隧道衬砌维修方案决策模型.该模型采用可辨识矩阵启发式约简算法对指标层进行客观定权,采用专家评判法对子目标进行主观定权,保证了求取权重的科学性.同时,该模型采用灰色理论中的多层次灰色综合评价法对既有铁路隧道衬砌维修方案进行综合决策,保证了决策结果的可靠性.实例应用表明,该方法可定量地得出所需结果,具有一定的推广价值.
Abstract:
The choice of maintenance project for existing railway tunnel lining crack is influenced by many fac.tors, including the investment costs, the natural environment and feasibility degree. In response to these fac.tors, this paper uses discernibility matrix heuristie reduction algorithm, expert evaluation method and multi.level gray comprehensive evaluation method to establish a comprehensive maintenance project for existing rail.way tunnel lining decision-making model. The model weights the Index layer objectively by using Matrix Re-duction Algorithm and weights the sub goals subjectively by using expert evaluation method, which ensures thescientific consideration of the weight, At the same time, the model decides the existing railway tunnel liningmaintenanee project comprehensively by using multi-level gray eomprehensive evaluation method to ensure thereliability of the results of decision-making. Examples of application show that the method can get the desiredquantitative results obtained, and it can be used more widely.
