摘要
地下工程数字化是是数字地球发展战略的一部分,是当前地下工程研究中的一个重要研究方向。在总结三维GIS、数字地层、三维地层可视化、地下工程虚拟现实系统等相关概念及研究的基础上,给出地下工程数字化的明确定义,即地下工程数字化就是以数字地层为依托,以信息化手段对地下工程建设过程中的勘察、设计、施工、监测等数据进行集中高效地管理,为地下工程的建设、管理、运营、维护与防灾提供信息共享和分析平台,最终实现一个地下工程全生命周期的数字化博物馆。地下工程数字化平台的系统体系应当由数据层、建模层、表现层、分析层、应用层等5个层次组成,并且应当采用组件式的软件开发方法进行开发。最后给出地下工程数字化在实际工程中的初步应用实例,并对地下工程数字化的进一步研究和发展进行探讨。
Digitalization of underground engineering is part of the development strategy of digital earth, and it is also one of the main new developing fields in the research of underground engineering. This paper first examines the concept and research of the terms such as 3D GIS, digital stratum, 3D strata visualization, and virtual reality of underground engineering. Then the concept of digitalization of underground engineering is clearly defined, that is, based on digital stratum and the technology of informatization, digitalization of underground engineering provides an integrated and effective way for the data management of underground investigation, design, construction, monitoring etc. in the construction process, and an information sharing and analytical platform for the building, management, running, maintenance and disaster prevention of underground engineering. The objective of digitalization of underground engineering is to build a digital museum of underground engineering for all life cycle. According to the concept, a system architecture of digitalization of underground engineering is then put forward. The system architecture is comprised of five levels, which are data layer, modeling layer, representation layer, analysis layer and application layer, and functionality of each layer is also described. It is also proposed that the software development of each layer should be implemented by component technology. Finally, some preliminary application examples of digitalization of underground engineering are put forward, and some research trends in thefuture are discussed, too.
