| 中文摘要: |
| 城市地道桥地势低洼，暴雨时易发生积水，不仅对交通产生较大影响，而且对不知水深进入地道桥的车辆、行人的生命财产安全构成威胁。通过对城市地道桥及周边小区域地形特征分析，改进了种子蔓延算法，解决了小区域汇水区域面积划分不准确的问题。通过对地道桥暴雨淹没的过程分析及汇水量与淹没深度计算，能快速模拟出积水区域并动态显示积水深度。通过对三维GIS软件skyline的二次开发，实现了对地道桥暴雨淹没分析及动态模拟，为市政排水及交通应急提供决策支持。 |
| 英文摘要: |
| The terrain of urban underpass bridges is relatively low, so its easily flooded in a rainstorm, which not only has great impact on transportation but also threatens the cars and peoples lives and propertied. Seed spread algorithm is improved by analyzing urban underpass bridge and surrounding small regions topography, and solves the issue that the accuracy of catchment area partition. Through the analysis of heavy rains flood process and calculation of water collecting amount and submerged depth, this method can quickly simulate the water area and dynamically display water depth. The submerging analysis and dynamic simulation of underpass bridge submergence is implemented through the secondary development of skyline, a 3D GIS software, which will provide decision support for municipal drainage and traffic emergency dispatching system. |
