摘　　要：水利数值模拟为水利业务提供可量化的决策支持,当前的单机模式存在标准规范不统一,使用方式不便捷,计算资源不高效的问题。基于已有的模型标准化工作,利用虚拟化、计算优化调度、Web Service、工作流及多维后处理技术,研发基于云计算的水利数值仿真模型计算服务平台,实现水利数值模拟云服务平台的资源动态部署、模型耦合计算,以黄河流域下游河道洪水演进数值模拟为例,进行并发计算应用测试,比较云服务模式和传统单机计算的效率。基于模型标准化的数值模拟云服务可以提供丰富便捷的前后处理工具,提高多用户并发任务的处理效率。Hydraulic numerical simulation can provide quantifiable decision support for water conservancy business. But there are problems such as no unified standards, inconvenient methods of use and inefficient computing resources in the current mode. Based on the existing model standardization, it proposes the integration, group coupling and dynamic computing service platform based on could-computing hydraulic numerical simulation, uses virtualized cluster to compute,Web Service,components and workflow and multi-field post-processing technology. The platform achieves the dynamic resource deployment and parallel computing of virtualized migrations in the cloud service platform of hydraulic numerical simulation, the coupling of model components and the flexible selection of the preprocessing and post-processing mode used the numerical simulation of flood evolution in the downstream river channel of the Yellow River basin as the example to achieve the multi-user and multi-type computing applications of multiple models on the cloud service platform, and compares the efficiency of cloud service computing model and traditional stand-alone computing via multiple schemes. The cloud service platform can provide a rich and convenient processing tools, improve the processing efficiency of multi-user concurrent tasks.
