Summary:The present invention relates to a composite dam and a construction method thereof. An upstream portion is formed as a fill zone constructed of a material such as sand, gravel, rock, soil, and the like, and a downstream portion is formed as a concrete zone constructed of concrete material to construct a composite dam by combining two different types of dams into one dam. A preferred embodiment of the present invention comprises: a fill zone formed to have a predetermined inclination toward an upstream side; a concrete zone formed to have a predetermined stepwise slope toward a downstream side; a transition zone formed between the fill zone and the concrete zone and having a clay liner formed therein; and an overflow cap formed at an upper end portion of the fill zone by concrete of a certain thickness. 본 발명은 상류부는 모래, 자갈, 암석, 토사 등의 재료로 축조한 필존과, 하류부는 콘크리트 재료로 축조한 콘크리트존으로 형성하여 2개의 다른 형식의 댐을 결합시켜 하나의 댐으로 형성하도록 하는 복합댐 및 그 시공방법에 관한 것이다. 본 발명의 복합댐의 바람직한 일 실시예는 상류측으로 일정 경사를 갖도록 축조되는 필존과; 하류측으로 계단상의 사면으로 일정경사를 갖도록 축조되는 콘크리트존과; 필존과 콘크리트존 사이에 축조되며 내부에 차수재가 형성되는 트랜지션존과; 필존 및 트랜지션존의 상단부에는 일정두께의 콘크리트로 형성하는 월류캡;을 포함하여 이루어진다.
