摘　　要：现代面板堆石坝以其独特的优越性在我国得到了广泛应用,但同时其病害率偏高,且病害检查及加固处理均存在一定困难,给面板堆石坝的发展带来不利影响。结合国内外面板坝设计及病害处理的丰富实践,对设计加固中的几个问题展开了探讨,提出如下建议:面板坝坝前辅助防渗铺盖可以取消,以便开展水下检查及加固;需要设置放空设施;周边缝宜取消中间止水同时加强顶部止水的防渗作用。Modern CFRD construction has developed rapidly in China due to its unique advantages,however the CFRD construction is restrained by high disease ratio and difficulties in danger inspection and treatment,which affects its future progress.Combing with the plentiful engineering practice of CFRD construction at home and abroad,we carry out discussion about several issues in CFRD construction,and put forward the following suggestions： the auxiliary water- proof blanket at dam front could be removed to facilitate the underwater inspection and reinforcement; the water empty facility is required,and the Intermediate water sealing in peripheral joint could be removed while the top water sealing should be strengthened.

关 键 词：防渗铺盖 放空设施 止水结构 面板堆石坝
