摘要
针对以往认为龙巴迪破损曲线是只与坝高有关的直线,没有将它与拱坝的安全性指标直接联系起来这一情况,从混凝土坝体的强度和屈曲稳定出发,得出两类曲线:一类与坝体混凝土的强度有关,是一簇以坝体混凝土强度为参数的双曲线;另一类与坝体的屈曲稳定有关,是一条指数曲线.
In consideration of the fact that the Lombardi curve does not rely on any safety indexes of arch dams but is only related to the dam height, two types of curves are presented based on the concrete strength of arch dams and the buckling of arch rings: the one is a group of hyperbolas, characterized by the concrete strength of arch dams; the other is an exponential curve related to the buckling of arch rings.
