【摘要】 以河海大学校园网格为例,介绍了网格计算平台的特点及其三层架构(资源层、网格层、应用服务层),说明了网格平台数值计算的实现途径。针对具体工程中的可靠度计算,提出基于Monte-Carlo方法随机边界元计算的网格实现;以某大型水电站厂房地下洞室群的可靠度计算,说明了这种网格算法的高效性。更多还原

【Abstract】 This paper took the case of a campus grid in Hohai university, and introduced the characteristic of grid computation and the three-layer frame of the campus grid such as resource layer, grid layer and application service layer, Then, the realization of the numerical computation was put forward. For the application of the reliability computing in engineering, there introduced a computing method on the grid platform of stochastic BEM based on Monte-Carlo method. Finally, an reliability computing example of an large-scale underground cavern group shows the high efficiency of this method.更多还原
