摘 要
本文为面混凝土面板堆石坝设计说明书，根据所给基本资料及面板堆石坝的特点进行调洪演算，本设计中一共选取了四种方案，经过调洪演算并结合下游防洪要求及经济因素等的考虑，最终选择方案四，即选择堰宽为75m的方案。
本设计主要进行了调洪演算、坝体分区设计、溢洪道设计、溢洪道水面线计算、坝体渗流分析及坝体稳定计算等几个方面。本设计中河岸溢洪道布置在河流右岸，为正槽溢洪道。大坝高71.3m，上游坝坡坡度为1.4，下游坡度为1.3坝轴线长度为449.4m，布置在河流转弯处。经坝体稳定分析和渗流计算，本方案满足要求。

ABSTRACT
This paper for the surface of concrete face rockfill dam design specifications, according to the basic information and given the characteristics of concrete face rockfill dam for flood regulating calculation, the total selection in the design of the four kinds of solutions, through the combined with the downstream flood control requirements for flood regulating calculation, and economic factors, finally four options, which chooses the plan of dam is 75 m wide.
This design mainly for flood regulating calculation, design, design of spillway, the surface spillway dam partition line, dam seepage analysis and dam body stability calculation. The design and arrangement of the spillway in the Banks of the river on the right bank of the river, spillway was right in the groove. 71.3 m high dam, the upstream dam slope degree is 1.4, the downstream slope 1.3 dam axis length of 449.4 m, decorate in the bend. This scheme by the dam seepage calculation, stability analysis and meet the requirements.
Keywords: concrete face rockfill dam, flood routing, design of dam body ,seepage calculation, Stability calculation, The bank spillway
