摘要
本文通过对过水围堰下游边坡混凝土护坡板各种型式的稳定和失稳过程的分析,把护坡板的稳定分为绝对稳定和准稳定;把护坡板的失稳归结为刚体平面运动。并由刚体平面运动方程,推导出混凝土护坡板的绝对稳定和准稳定条件关系式,以确定护坡板的尺寸。
Tnis paper investigates the various forms of stabilities and the processes of the motion of concrete blocks laying on the downstream slopes of overtopped rockfill cofferdams and presents the new concepts of absolute-stability and quasi-stability.The motion of the block is reduced to the stiff-body motion on plane.The formulas are derived for the conditions of concrete blocks absolute-stability and quasi-stability according to the equations of stiff-body motion on plane.
