The invention discloses a concrete gravity dam used for a steep river valley terrain. The concrete gravity dam comprises an original terrain line, a right bank guide wall, a left bank guide wall, a riverbed dam section, a right bank grouting adit, a left bank grouting adit, a right bank slope curtain grouting layer, a riverbed curtain grouting layer, a left bank slope curtain grouting layer, an upstream expansion wall, a downstream expansion wall and a dam axis. The concrete gravity dam used for the steep river valley terrain has the beneficial effects that the construction difficulty and engineering quantity of the concrete gravity dam for a steep river valley of a high slope can be remarkably reduced, the construction risk is reduced, the construction cost is saved, and the constructionperiod is shortened. 本发明公开了一种用于陡峭河谷地形的混凝土重力坝，包括原地形线、右岸右岸先导墙、左岸先导墙、河床坝段、右岸灌浆平硐、左岸灌浆平硐、右岸坡帷幕灌浆、河床帷幕灌浆、左岸坡帷幕灌浆、上游扩展墙、下游扩展墙、坝轴线。本发明有益效果是能够显著的减小高边坡陡峭河谷混凝土重力坝施工的难度和工程量，减小施工风险，节约施工成本，缩短施工工期。
