从 RCC坝渗流原因分析入手 ,阐述了高 RCC重力坝对防渗结构的要求 ,即防渗结构必须简单、安全可靠、经济耐久 ,对环境无污染 ;必须能有效地控制坝体渗漏量和降低层面扬压力 ;必须与坝体施工互相协调 ,减少干扰 ,以利于坝体快速施工 ;必须具有良好的整体性和强度 ,防止坝面裂缝的扩展 ,说明对龙滩高 RCC重力坝进行渗流分析和防渗结构研究的必要性 ,此外 ,简略介绍了“九五”国家重点科技攻关项目在这方面的部分研究成果
Beginning with the analysis of seepage reasons of RCC dam, the requirements for seepage control structure of high RCC gravity dam are expounded, that is, seepage control structure must be simple, safe and reliable, economical and durable, and pollution-free to the environment; it is necessary to effectively control leakage and Reduce the level of uplift pressure; must coordinate with the construction of the dam to reduce the interference in order to facilitate the rapid construction of the dam; must have good integrity and strength to prevent the expansion of the dam surface, explain the Longtan RCC gravity dam for seepage analysis And the necessity of research on seepage control structure. In addition, some research results in this regard in the Ninth Five-Year Plan
