摘要
针对铁路隧道洞口工程变化多、工程数量计算复杂以及传统二维设计方式不直观等问题,研发了一种基于三维场景开发的洞口方案设计系统。该系统以隧道设计数据为核心,搭建隧道参数化构件库,交互式设计隧道边仰坡、洞门结构、防护结构等,快速实现隧道洞口方案设计,还可以统计工程量。通过人工智能手段还可以快速识别隧道洞口偏压。经过工程应用验证,该系统技术方案可行,能明显提高隧道洞口方案设计的工作效率和质量。
In response to the problems of frequent changes in railway tunnel portal engineering,complex calculation of engineering quantities and the inadequacy of traditional 2D design methods in terms of clarity,a portal scheme design system based on 3D scene development was proposed.By sorting out the design process and functional requirements,the key modules and functional architecture of the system were designed.The system generates a 3D spatial scene based on 3D terrain data and creates tunnel components parameterized by design data.It enables interactive design of tunnel slope,support measures and statistical calculation of related engineering quantities,thereby enabling rapid 3D design of tunnel portal engineering.The system can also quickly identify the bias voltage at the tunnel entrance by AI.The engineering application verification shows that the tunnel portal scheme design system based on 3D scene is feasible and can meet professional requirements,and can significantly improve design efficiency and quality.
