Abstract
Being the largest multi-purpose dam project in the world to date which offers wide-range of benefits,the Three Gorges Project has played a dominant role since impoundment and power generation in 2003.The decision and implementation of Phase III pilot project of upstream roller compacted concrete cofferdam are reviewed,including working process of targeting at"double zero"quality and safety management goals.Through engineering layout design and construction technology innovation,the RCC cofferdam construction in the upper reaches of the third phase of the Three Gorges Project can achieve water retaining power generation and bring into play the benefits of hydropower projects in advance;the upstream and downstream cofferdams of the Yantan Hydropower Station,as a demonstration project for the production test of RCC cofferdams in the upper reaches of Three Gorges Phase III,provide support for the decision of the construction plan of RCC cofferdams in Three Gorges Phase III,and also form a Chinese plan for continuous construction of the whole section,big storage surface and thin layer of RCC dams;the construction method of grouting modified composite concrete invented in the construction of seepage prevention layer upstream of RCC cofferdam of the Yantan Hydropower Station has become the first technology and practical experience in China.It helps to realize that the Three Gorges Project is the one that had followed the path of high-level technological self-reliance and self-improvement.It is a project that integrates technical and managerial innovation.Inheriting and developing the culture and spirit contained in the Three Gorges plays an key role in promoting high-quality development of hydropower industry in China.The project is also valuable for innovative development of hydropower and new quality productivity in high-altitude areas.关键词
