摘要: 本文在分析传统道路与建筑物空间冲突算法的基础上,借鉴其优点,从保持建筑物间的整体空间布局特征,以及模拟人工移位的处理方法角度出发,提出根据区域密集程度的不同,划分为稀疏区、密集区、高密集区三个等级区域,并制定相应的多层次移位处理原则,然后,根据道路与建筑物的邻近程度,将建筑物分为多等级的移位层,对移位层内的冲突进一步细分;据此,依据移位层的邻近程度,将多层次处理原则贯穿于要素冲突外力的计算、外力的聚合以及其移位算法的确定中,分别对道路与建筑物的冲突、建筑物之间的冲突分别进行处理。

Abstract: By analyzing the advantages of traditional algorithm of disposing the spatial conflict between roads and buildings, one new method is brought forward, which refers to simulating the method of manual displacement and keeping the general spatial layout of the buildings well. Firstly, the multilevel spatial disposal principles between the roads and buildings of different regions are put forward in terms of the difference of region density. The multilevel spatial disposal principles refer to three levels: one is to keep the origin distance scale, spatial relation and spatial layout in the sparse region, the other is to keep the minimal distance and spatial orientation relation in the dense region, the third is to only keep the minimal distance in the high-dense region. Then, the displacement layers of buildings are built according to the neighbor degree between buildings and roads. And the displacement operation will be executed respectively according as fore-and-aft displacement layer order. When disposing the conflict and displacing the buildings, the multilevel spatial disposal principles spread through the calculation and aggregation of extern forces and the design of displacement algorithm on the buildings. The spatial conflicts between the road and building, and the conflicts between the buildings, are disposed especially.
