摘　　要：最优化技术在决策分析中占着极重要的位置。层次分析法(AHP)是将决策总是有关的元素分解成目标、准则、方案等层次,在此基础之上进行定性和定量分析的决策方法。基于群组层次分析法的评价指标体系设计方法,它既能体现层次分析法(AHP)的优点,又能较好地弥补层次分析法AHP法的不足。本文以厦门海底隧道为工程背景,就海底隧道埋深提出了基于群组层次分析法。拟请一组专家对影响海底隧道厚度的因素进行评价,根据专家的判断能力,给出判断力权值,得到最小岩石覆盖厚度的重要性因子,给出不同方法的权值,经加权分析后最终确定最小岩石覆盖厚度。Optimization technology is an important method in the decision-making analysis.Analytical Hierarchy Process（AHP） is a decision-making method.It divides the elements of decision-making into objectives,guidelines,programs and other levels.On the basis of these,some qualitative and quantitative analyses are being carried on.The evaluation index system method based on the group＇s level of AHP not only reflects the advantages of the AHP,but also makes up for the disadvantages.An AHP based on the group＇s level was put forward to determine the rock covering thickness of the sub-sea tunnels.According to the AHP,a specialist panel should be invited to evaluate the factors which affect the thickness of the sub-sea tunnels.Weight of each the specialists’ judgment is decided according to the ability of the specialists to suggest the most optimized matrix.The minimum thickness of rock covering would be determined finally by the weighted analysis.The new method is named as the AHP of the rock covering thickness of the sub-sea tunnels.This method was applied to analyze the rock covering thickness of Xia ’men sub-sea tunnel.
