摘要
溪洛渡拱坝高273m,拱肩槽开挖高边坡最高约250m,其整体稳定性是复杂的空间问题。作者采用三维有限元方法对拱肩槽边坡的应力场和位移场进行了模拟,计算结果表明:该方法能较全面、真实地反映实际情况,为工程高边坡的整体稳定性评价和坡比设计提供依据。
The maximum dam height of the Xiluodu hydropower station is 273 m. The excavation of the spandrel groove forms a slope 250 m high, whose stability is a complicated space problem. The method of three-dimensional finite element analysis is used to simulate the stress and displacement field of the spandrel groove high slope in the paper. The calculated results indicate that the method can reflect the reality well and supply the basis for the design of slope ratio and the stability evaluation of the engineering high slope.
