接缝简化模型及参数对面板堆石坝面板应力及接缝位移的影响研究
|
摘要
通过大量的三维面板堆石坝有限元分析,研究不同止水结构形式对面板堆石坝面板应力和接缝位移的影响。在此基础上,建议简化的面板堆石坝接缝模型,简化模型具有简单的表达形式和较少的参数,方便面板堆石坝的有限元计算分析,可满足精度要求。通过对简化模型参数进行敏感性分析,建议简化模型参数取值范围和改善面板应力的工程措施。
The effects of different water seal structures on stress of facing slab and joint displacements of concretefaced rockfill dam(CFRD)are studied through a large number of three-dimensional finite element analyses. Furthermore,a joint simplified model which is simpler and has fewer parameters is proposed.And it has a good accuracy.Therefore,it makes finite element analysis of CFRD easier.In addition,a range of parameters of simplified model and engineering measures for improving the stress of facing slab are proposed by a sensitivity analysis of parameters.
