摘要
在地下管线设计的过程中,需要计算相邻已建管线之间的碰撞状态或空间距离;另外,应尽量将管线布置在工程地质条件较好的地层中.数字地下空间与工程理论的提出,为解决上述问题提供了一个很好的思路,将城市道路、地下管线和数字地层三者耦合叠加,建立一体化的存储结构和三维空间分析方法.核心技术包括数据存储结构、三维空间距离算法和断面综合分析,为三维环境下的地下管线实时、动态设计提供数字化服务.
In the process of a subterranean pipeline design, it＇ s necessary to calculate the interference or spatial distance with neighboring existing pipelines; moreover,the subterranean pipeline had better be distributed in the stratum of good geological condition. The application of digital underground space and engineering provides a new method to resolve the mentioned problems. It couples urban roads, subterranean pipelines and stratum together by standard storage format as well as a series of key spatial analysis algorithms, which consist of integrative data structure, spatial distance arithmetic and break surface synthetic analysis. The digital designing service of subterranean pipeline is real-time and dynamic.
