| 摘 要： | 黄河大柳树坝区构造属加里东期形成的地槽褶皱系,其上由泥盆系—三叠系组成盖层,相应地形成地台型褶皱带。坝区发育盖层性断裂,切割较浅。坝区受夜明山马长梁背斜控制,岩层变形强烈,节理、裂隙发育,加之风化较深,岩体完整性差。鉴于坝区构造总体上连续而完整,变形破裂主要为原生,故仍不失其建坝条件。

| Abstract: | The regional structure of the Dailushuba area of the Yellow river is a geosyncline zone which was formed during the Caledonian. The Devonian-Triassic cap formed a platformal fold belt. In the dam area, a fault cuts the cap. The dam area is controlled by the Yemingshan-Machanliang anticline. and the deformation is strong, joints and fractures are developed. Weathering zone extends to the depth, the rock body is non-intact. The tectonic as a whole however is continuous and consistant. Although the structure is complex, the conditions of building a dam are acceptalbe. |
