地下综合体及地下管廊水灾模拟数据集

采用HYSWMM进行模拟。地表降雨模拟是个复杂的综合性工程，且模拟范围较大，只能考虑到对降雨、排水等影响较大的建筑物、排水管道以及绿地等，同时在模拟中考虑了地面坡度、地形地势、雨水管网收集方向等，并根据研究对象，将地铁出入口单独划分为汇水区。同时，采用HEC-RAS软件对深圳市车公庙综合交通枢纽站厅层及站台层的水灾过程模拟及分析。通过GIS提取坐标、地形数据、横断面信息等，出入口通道和内部通道的阶梯均简化为斜面，并输入相应的断面信息。模拟同时考虑了站台层及站厅层两层。数据量约5GB。

Simulations were first conducted using HYSWMM. Surface rainfall simulation is a sophisticated and comprehensive engineering endeavor. Given the large-scale simulation scope, only critical factors including buildings, drainage pipelines, and green spaces that exert significant impacts on rainfall and drainage processes were taken into account. Furthermore, ground slope, topographic features, and the collection direction of the stormwater pipe network were incorporated into the simulation. Additionally, subway entrances and exits were separately delineated as catchment areas based on the research targets. Meanwhile, HEC-RAS was utilized to simulate and analyze the flood progression within the concourse and platform levels of the Chegongmiao Comprehensive Transportation Hub in Shenzhen. Coordinates, topographic data, cross-sectional information and other relevant datasets were extracted via GIS. The stairs of both the entrance/exit passages and internal passages were simplified as inclined planes, with corresponding cross-sectional parameters input into the model. The simulation covered both the platform and concourse levels. The total size of the dataset is approximately 5 GB.
