基于BIM的动态逃生路径算法在非居建筑中的应用

Application of dynamic escapepath algorithm based on BIM in non-resident construction

利用BIM中的信息建立非居建筑特征数据模型。介绍最短枝桠发芽算法,演示将其应用于动态逃生路径算法时的计算步骤。以上海某电力工程项目为例,使用最短枝桠发芽算法实时计算非居建筑最佳的三维逃生路径。该算法能够快速、有效地选择最优逃生路径,为灾害时设施内的人员争取更多的疏散时间。

Numerical feature model of non-resident construction was built by information from building information modeling （BIM）. The shortest branches sprouting algorithm was introduced, and the application of the algorithm in dynamic escape path algorithm was illustrated. Taking a power engineering project in Shanghai as an example, the best 3D escape path of non-resident construction was calculated real time by the shortest branches sprouting algorithm. The algorithm can choose the optimized escape path fast and effectively, and gain more time for evacuation.
