摘　　要：为将以往隧道案例的经验应用到新建隧道设计中,以解决传统设计方法工作量大且效率低下的问题,提出基于案例推理的隧道洞门智能设计方法。结合隧道洞门工程特点,选取影响洞门设计的主要因素,将影响因素划分为12个属性单元来表征工程案例,运用三角模糊数的层次赋权计算方法对各属性单元权重进行赋值,借助相似度理论建立隧道洞门设计方案相似决策模型。基于GIS技术开发了隧道洞门工程案例库,实现对既有工程的存储管理,同时利用SQL查询语言及Python计算脚本实现案例的属性特征值计算与最相似匹配,进一步修正后可实现隧道洞门修建方案的设计决策。以某山区隧道为例对智能设计方法进行验证,结果表明:根据属性单元特征值计算结果,在案例库中比选得出与拟建隧道相似度最高的既有工程为凤凰山隧道,且相似度为0.707。因此,设定阈值为0.7时能加快案例库的检索速率与匹配准确率,该方法吸取了既有工程案例的经验,能应用于隧道洞门施工方案的决策设计,可供今后隧道洞门方案的智能化设计参考。In order to apply the experience of previous tunnel cases to the design of new tunnels to solve the problem of heavy workload and low efficiency of traditional design methods,an intelligent design method of tunnel portals based on case-based reasoning is proposed.Combined with the characteristics of tunnel portal engineering,the main factors affecting tunnel portal design are selected,and the influencing factors are divided into 12 attribute units to represent the project cases.The weight of each attribute unit is assigned by using the hierarchical weighting calculation method of triangular fuzzy number,and the similarity decision-making model of tunnel portal design scheme is established by using the similarity theory.Based on GIS technology,the tunnel portal project case base is developed to realize the storage and management of existing projects.At the same time,the SQL query language and Python calculation script are used to realize the calculation of case attribute eigenvalue and the most similar matching.After further modification,the design decision of tunnel portal construction scheme can be realized.A mountain tunnel is taken as an example to verify the intelligent design method,the results show that:according to the calculation results of attribute unit eigenvalue,the existing project with the highest similarity to the proposed tunnel is Feng Huang Mountain Tunnel,and the similarity is 0.707.Therefore,when the threshold value is set to 0.7,the retrieval rate and matching accuracy of the case base can be accelerated.This method draws on the experiences of existing engineering cases and can be applied to the decision-making design of tunnel portal construction schemes and used as a reference for the intelligent design of tunnel portal schemes in the future.
