文章以新疆北疆山口电站为实例,结合该电站常态混凝土双曲拱坝址的地形和地质条件,通过分析确定拱冠梁顶部、中部、底部的尺寸,坝肩拱端嵌深和倒悬度,以及拱圈线型选择等问题,进行坝型设计及优化,并对高拱坝体形设计的设计思想、设计方法和设计原则等进行了阐述,最终确定该拱坝体型为双曲拱坝,以期对类似工程有一定的参考和借鉴价值。
Taking the Shankou Power Station in the northern part of Xinjiang as an example, the top, middle and bottom dimensions, the embedment depth and the overhanging abutment of the arch abutment were analyzed by analyzing the topography and geological conditions of the normal concrete double curvature arch dam site. As well as the arch ring linear selection and other issues, the dam design and optimization, and the design concept of high arch dam body shape, design methods and design principles are described, and ultimately determine the arch dam body is double curvature arch dam , With a view to similar projects have some reference and learn from the value.
