摘要
研究目的:随着“四纵四横”“八纵八横”铁路网的基本成型,铁路传统建造技术已然成熟,但对于设计、施工、建设以及运维一张图仍停留在理论构想阶段,铁路精细化设计、全监控施工、智能化运维等方面的软实力仍是短板,也是制约我国自主数字铁路工程乃至智能铁路体系建设的根本瓶颈。随着物理世界AI智能化水平的迅猛发展,铁路工程走向协同化、数字化、智能化也是必然的发展趋势。针对目前我国铁路信息化短板,提出数字资产一张图的铁路协同勘察设计建造运维体系构想,本文主要思路为铁路沿承数字地球、数字城市的技术脉络,以3DGIS平台为基础框架,构建起数字铁路工程资产,实现孪生铁路在计算机中的表达。研究结论:(1)以GIS与BIM设计构建起来的“宏-微”观两级演化,具有信息化无缝衔接全阶段全过程、空间布局设计与结构设计实现松耦合、单尺度静态表达向多尺度动态表达等显著优势;(2)以三维选线系统自动化模型构建为核心的数字资产应用体系,主要解决普适资产的接入与全真、高效表达;(3)“宏-微”观两级演化勘察设计体系的构建将极大地促进自动化设计创新;(4)本研究成果可为铁路正向BIM设计与施工、运维奠定基础。
Research purposes:With the basic formation of the"four vertical and four horizontal"and"eight vertical and eight horizontal"railway network,traditional railway construction technology has matured,but one map for the design,construction,construction,and operation and maintenance is still at the theoretical conceptual stage.The soft power in terms of fine design,full-monitoring construction,and intelligent operation and maintenance of railways is still a shortcoming,and it is also the fundamental bottleneck restricting the construction of independent digital railway engineering and intelligent railway system in China.With the rapid development of AI intelligence in the physical world,it is also an inevitable development trend for railway engineering to become collaborative,digital,and intelligent.In view of the current shortcomings of China's railway informatization,this paper proposes the concept of railway collaborative survey,design,construction,operation and maintenance system with one map of digital assets,the main idea is that the railway follows the technical context of digital earth and digital city,and uses the 3DGIS platform as the basic framework to build digital railway engineering assets and realize the expression of twin railways in computers.Research conclusions:(1)The two-level evolution of"macro-micro"view constructed by GIS and BIM design has the characteristics of seamless connection of informatization in the whole stage and the whole process,loose coupling of spatial layout design and structural design,and single-scale static expression to multi-scale dynamic expression.(2)The digital asset application system centered on automated modeling of 3D route selection system mainly aims to solve the problem of universal asset access and realistic and efficient expression.(3)The construction of the"macro micro"two-level evolutionary exploration and design system will greatly promote innovation in automated design.(4)The research achievement can lay the foundation for the forward BIM design,construction,and operation of railways.
