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.
