在对Snake模型研究的基础上，结合建筑物群在移位中的特点，从2个方面对Snake模型进行改进：首先，在Snake模型中加强对齐排列建筑物群这一重要空间特征的识别，以便保持对齐排列建筑物群在移位前后不变；其次，针对传统Snake模型有时无法解决两个建筑物空间冲突的缺点，对街区中的建筑物群实行分层次移位，先将有冲突的两个建筑物作为整体，与剩余其它建筑物利用Snake模型一起移位，然后再根据文中提出的建筑物间相互冲突的4种受力模型，进行建筑物间空间冲突的移位。最后利用改进的Snake模型进行移位实验和分析。%Based on the research of snake model ,it presents two improvements on snake model applied to the building cluster displacement .Firstly ,in order to protect the important spatial relationship ,buildings alignment ,a method that strengthens the identification of alignment is proposed to maintain the spatial relationships in the displacement .Secondly ,against the weakness of snake model that can not solve the conflicts between buildings ,hierarchical displacement of buildings cluster is implemented to improve the computer method of conflict force between buildings ,and fourth force models are proposed to displace buildings in conflict with other buildings .Finally ,the improvement snake model is used in displacement experiment and the result is analyzed .
