中文摘要：

最佳的撤退计划基于水坝裂缝洪水被学习数字模拟。数学模型与液体(VOF ) 的体积相结合的一个三维的水坝裂缝方法被采用。根据从数字模拟和撤退紧急情况计划的选择原则获得的水力的信息，撤退线路分析模型被建议，它由道路权利模型和随机的度模型组成。道路权利模型被用来在道路计算消费时间，并且随机的度模型被用来判定道路是否被堵住。然后，最短的撤退线路基于 Dijstra 算法被获得。位于深圳的 Gongming 水库作为一个盒子被拿学习。结果显示出那个工业区域我在 2 500 s 被充满，并且在 5 500 s 以后，大多数工业区域 II 被沉没。Hushan，劳昆·福雷斯特和 Chaishan 没在工业区域附近被充满我和 II。基于上述分析，最佳的撤退计划被决定。

英文摘要：

The optimal evacuation scheme is studied based on the dam-break flood numerical simulation. A three- dimensional dam-break mathematical model combined with the volume of fluid （VOF） method is adopted. According to the hydraulic information obtained from numerical simulation and selecting principles of evacuation emergency scheme, evacuation route analysis model is proposed, which consists of the road right model and random degree model. The road right model is used to calculate the consumption time in roads, and the random degree model is used to judge whether the roads are blocked. Then the shortest evacuation route is obtained based on Dijstra algorithm. Gongming Reservoir located in Shenzhen is taken as a case to study. The results show that industrial area I is flooded at 2 500 s, and after 5 500 s, most of industrial area II is submerged. The Hushan, Loucun Forest and Chaishan are not flooded around industrial area I and II. Based on the above analysis, the optimal evacuation scheme is determined.
