土石坝由于对地基具有良好的适应性、能就地取材及充分利用建筑物开挖渣料、造价较低、水泥用量较少等优点,是西部地区一批拟建高坝的重点比选坝型。糯扎渡高心墙堆石坝的成功建设,解决了250 m级土石坝重大关键技术难题。本文通过系统总结已建成的糯扎渡等高心墙堆石坝建设的经验,凝练高土石坝建设面临的变形控制、渗流控制、坝坡抗滑稳定、泄洪安全及控制、大坝安全建设与质量控制、安全评价及预警等关键科学技术问题,全面深入论述了已有的研究成果和基本结论,为未来300 m级高土石坝建设提供参考和重要的技术支撑。
Due to its good adaptability to the foundation, the earth-rock dam can draw materials locally and make full use of the excavated materials in the building, the cost is lower and the amount of cement used is less. It is the first choice for a number of proposed dam projects in western China type. The successful construction of Nuozhadu high core rockfill dam solved major key technical problems of 250 m earth-rock dam. This article systematically summarizes the construction experience of Nuozhadu CFRD, concludes the deformation control, seepage control, slope stability, flood safety and control, construction of dam safety and Quality control, safety assessment and early warning, and other key scientific and technological issues, the existing research results and basic conclusions are thoroughly discussed in depth, providing reference and important technical support for the construction of 300m high earth-rock dam in the future.
