道路平面交叉平面设计与软件实现
[摘要]道路与道路交叉通常可分为立体交叉和平面交叉两大类。随着交通建设的飞速发展,高速公路等全封闭式道路的建设逐渐趋于缓和,非全封闭式道路建设逐渐成为当前道路建设的主要任务。由于非全封闭式道路间的交叉大多可采用平面交叉,因此,平面交叉的建设不可避免的呈上升趋势。平面交叉平面设计各构件关联性较强,相互影响制约,修改时常常牵一发而动全身,传统设计难以实现实时联动调整,耗时长,重复利用率低,严重浪费社会资源。因此,研究一套可实时交互设计、检验、绘制且可移植等功能的设计软件是迫切的,是有实用、商业及社会价值的。

[abstract] road and road intersection usually can be divided into two categories, interchange and plane cross. With the rapid development of traffic construction, fully enclosed road construction such as highway gradually easing, not fully enclosed road construction gradually es the main task of the current road construction. Due to the fully enclosed road intersection between mostly can adopt plane cross, therefore, planar cross construction inevitably is on the rise. Plane intersection plane design ponent relevance is stronger, influence each other, when a change is often inescapably, traditional design is difficult to realize real time linkage adjustment, time consuming, repeated utilization ratio is low, serious waste of social resources. Therefore, a set of research can be real-time interactive function such as design, inspection, mapping and portable design software is urgent, there is a practical, commercial and social value.
