研究目的：在道路工程三维设计系统中,选择合适的路基工程设计模式对路基设计模块的构架、开发以及应用有重要意义。本文通过研究道路工程三维设计系统中的多种路基工程设计模式,提出适宜的设计模式以及相应的系统开发总体解决方案。
研究结论:从理论上将道路工程三维设计系统中的路基工程的设计模式分为真三维设计模式、准三维设计模式和伪三维设计模式。通过对生产需求、路基工程特点、设计理念转变、既有资源利用、项目综合投入等多方面分析,采用准三维设计模式开发三维路基工程设计模块是适宜的。在一定条件下,将准三维设计模式和伪三维设计模式统筹考虑、分步实施,也是可行的。
Research purposes: With 3D system for the road engineering design, choosing the appropriate subgrade engineering design mode is essential to framing the subgrade design model and its development and application. By studying variable design modes for road subgrade engineering with 3D software system, this paper proposes the appropriate subgrade designmode and the corresponding overall solution to the system development.
Research conclusions:In 3D software system for the road engineering design, the designmode for road subgrade can be divided into threemodes theoretically, namely pure -3D designmode, quasi-3D designmode and pseudo-3D design mode. Through a comprehensive analysis of the production requirements, subgrade engineering characteristics, change of design concep,t usage of resource and synthetic investmen,t it shows using quasi -3D design mode to develop subgrade engineering design software is appropriate, and under certain conditions, using quasi-3D designmode along with pseudo-3D designmode step by step is also feasible.
