| 摘 要： | 官地水电站上游围堰最大堰高55m，总填筑方量约100万m3，结合工程实例及现场情况确定为斜墙土石围堰，防渗型式采用复合土工膜与封闭式防渗墙。在施工阶段由于现场料源问题，采用土工格栅加筋设计，计算及实践证明了设计的合理性和安全性，可以为其他类似工程借鉴。

| Abstract: | Guandi Hydropower Station upstream cofferdam has maximum height of 55m.Total filling quantity is 1 million cubic metres.Project examples and site conditions are combined for determining the project as sloping core earth-rock cofferdam.Composite geomembrane and closed type cut-off wall are adopted as impermeable model.Geogrid reinforced design is adopted during the construction stage due to on-site source material problem.Design rationality and security are proved by calculation and practice,thereby providing reference for similar projects. |
