| 中文摘要: |
| 为增强土石围堰溃堰洪水演进计算数据及结果的直观性与处理的同步性，耦合土石围堰溃堰洪水数值模拟模型和溃堰动态仿真模型构建了土石围堰溃堰洪水演进动态仿真架构，其中考虑了洪水演进水力要素、洪水演进过程和河槽空间位置等特征信息。建立了数值模拟数据及三维动态仿真数据与相应图元对象的映射关联，通过动态更新水位、围堰及河道等图元变量和属性变量，直观地表现了土石围堰溃堰洪水演进的时空分布特征，为防洪减灾的决策分析提供了交互式可视化平台。 |

| For enhancing the visibility and synchronicity of numerical calculation results of earth-rock fail?
ure flood propagation，the dynamic simulation framework of failure flood propagation is established by cou?
pling the flood mathematical simulation model with the dam failure dynamic simulation model. A correlation
mapping of numerical simulation data and 3D dynamic simulation data onto corresponding graphics primitive
elements is built. The spatial-temporal distribution characteristics of flood propagation of the earth-rock cofferdam failure can be directly perceived by dynamically updating the graphics primitive variables and property variables，such as water level，cofferdam and river channel. |
