| 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。

Discussion on several issues of concrete face rock-fill dam |

| Abstract: | Modern CFRD construction has developed rapidly in China due to its unique advantages , however the CFRD con-struction 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 . |
