摘　　要：结合具体工程的设计，介绍了一种结构合理、安全可靠、能充分发挥建筑材料强度的连拱箱式硬壳溢流坝，经过与实体重力坝比较，可节约投资21％，经济效益显著。该工程经过几年运营，经受了洪水考验，实践证明，非均质硬壳溢流坝在西北地区多泥沙河流上的运用是成功的，具有广阔的发展前景。Combining with an actual project design, this paper introduces a multi-arch-box type hard-faced overflow dam which is reasonable in structure, safe and effective in utilizing the strength of construction materials sufficiently. Compared with a solid gravity dam, it can save investment cost of 21%, and has obvious economic benefit. Through several years operation of this project, it has stood a severe test of floods. The practice shows that the non-uniform hard-faced overflow dam is suitabe for overloaded rivers in the northwest region of China, and has a vast developing prospect.
