摘要
介绍向家坝工程中重要的临时建筑物一期和二期土石围堰工程的特点、围堰的平面布置、断面形式、结构及防渗体系的设计、施工与运行情况。应用结果表明,复合土工膜防渗性能和力学性能十分优越,适应性强,在向家坝围堰工程防渗中取得了良好的效果。
The engineering characteristics, plane layout, sections, strueture, and seepage prevention system earth-rock fill cofferdam in the first and second phase of the project are introduced. This is one of the most important temporary hydraulic structttres of the Xianjiaba Hydropower Station. The application results show that the anti-seepage capability and mechanical properties of composite geomembrane are extremely superior, and also have strong adaptability. The composite geomembrane has been used in the earth-rock fill cofferdam in the Xiangjiaba Hydropower Station, to good effect.
