摘要
面向铁路全生命周期沿线地理地质环境精准感知需求,针对持续变化的铁路地理与地质数据长期以来各自独立表达、分散管理、难以深度融合等问题,提出了铁路地理地质数据"本体域-变化域-状态域"三域关联的集成表达模型,首先,以地理地质环境要素"时空变化"链式关联为中心,定义了时空变化的参与者(要素)、驱动力(事件)和呈现模式(过程),然后,定义了状态级-实体级-过程级多层次时空变化关联关系,构建了轴面一体的铁路地理地质数据知识图谱,描述了"状态域-变化域-本体域"纵向映射轴、"对象-事件-过程"横向关联面之间的轴面关联关系,提出了知识图谱引导的"状态级-实体级-过程级"时空变化多域关联.以铁路高陡边坡施工典型应用为例,分析了该模型的可行性,进一步证明其重要意义和巨大应用潜力.
Abstract
Objectives:Facing the needs ofdigital twins for the whole life cycle of railway,the problems exist in independent expression,decentralized management and difficult in-depth integration of the continuously changing railway geographic and geologic data for a long time.Methods:This paper takes railway geo-graphic and geologic elements as an inseparable whole,and proposes an integrated expression model of the three-domain association for railway geographic and geologic data,which includes ontology domain,change domain and state domain.First,it takes spatial-temporal change as the center and defines the change participants(elements),drivers(events)and presentation modes(processes).Then,it defines a multi-level spatial-temporal change association relationship between state level,entity level and process level.Finally,it constructs a knowledge graph of railway geologic data with multi-domain association,and finely portrays the semantic association relationship between three aspects of geological elements,events and processes.Results and Conclusions:The importance and potential of the model in typical tunnel con-struction applications are analyzed.
