铁路隧道洞口设计需要综合考虑多种因素的影响,传统的设计图纸资料存储难以满足隧道工程信息化发展的需求。本文提出隧道洞口设计案例和设计规范知识图谱构建方法,可对隧道洞口设计知识进行可视化管理和智能化查询。首先,结合隧道洞口设计经验,系统分析隧道洞口设计影响因素;分别定义隧道洞口影响因素和设计规范上下位关系,按照知识图谱三元组规则,建立隧道洞口设计案例和设计规范知识图谱模式层;在此基础上,收集大量洞口设计案例和设计规范,按照知识图谱模式层,构建隧道洞口设计案例和设计规范知识图谱。在知识图谱的基础上,搭建隧道洞口智能问答系统,可以进行隧道洞口设计知识的搜索查询和智能问答。最后,通过设计案例证明方法的可行性和通用性。

The design of railway tunnel portals requires a comprehensive consideration of various factors,and traditional design drawing data storage is difficult to meet the needs of information technology development in tunnel engineering.In response to this challenge,a novel methodology has been proposed to construct a knowledge graph specifically dedicated to tunnel entrance design cases and design specifications,which can visually manage and intelligently query tunnel entrance design knowledge.Firstly,based on the experience of tunnel portal design,the influencing factors of tunnel portal design were systematically analyzed.The hierarchical relationship was defined,and a knowledge graph pattern layer for tunnel portal design cases and design specifications was established according to the knowledge graph triplet rule.On this basis,a large number of tunnel portal design cases and design specifications were collected,and a knowledge graph of tunnel portal design cases and design specifications was constructed according to the knowledge graph pattern layer.On the basis of knowledge graph,an intelligent question and answer system for tunnel portal design was built,which can search and query the knowledge of tunnel portal design and provide intelligent question and answer.The feasibility and universality of the method were demonstrated through a design case.
