静力三分力系数用于描述风对桥梁的静力作用,气动导数是颤振和抖振分析方法的核心。 - These landslides go with fluidization peculiarity different degree in course of their motion , and their speed and distance increase several times because of the fiuidization , thereby the disaster area greatly broaden . on the base of above , the paper studies systematically the fluidization of large high - speed rockslides in all its aspects : analyzed the aerodynamic effect in the short - range on the base of the wind turmel experiment , studied the effect of falling into pieces when landslides collides mountain ; studied the accelerating effect through high - speed collide experiment of landslides model ; and the paper reappear the overall process including set - out , collide in the short range , debris flow in the long - range of touzhai large landslide via distinct element method ( dem ) , studied the flow law and equation of different type of debris flow resulted from large landslide . as a sample to apply , the paper analyzed fluidization mechanism of touzhai landslide
基于这一点,本文对大型高速岩质滑坡的流体化现象进行了全面而系统的研究:通过风洞模型实验,研究了大型高速滑坡凌空飞行阶段的空气动力学效应,研究了飞行中滑坡岩体在与途中不动山体发尘碰撞时的解体破碎效应,通过滑坡岩体高速碰撞模型实验研究了滑坡岩体解体破碎后部分岩体的加速运动效应,并应用离散单元法再现了云南头寨沟大型滑坡启动高速、近程碰撞、远程碎屑流运动的全过程,研究了岩体解体破碎后形成不同类型碎屑流的运动规律及运动方程,并对头寨滑坡流体化运动机理进行了实例分析,取得了以下主要结论和成果: ( 1 )对于大型高速滑坡,大多在启程活动阶段已获得了高速,这使得这类滑坡在其离开剪出口之后以凌空飞行的形式向前运动,在其飞行过程中,滑坡岩体与空气强烈作用,并产生空气动力学效应,滑坡岩体在因碰撞而产生的解体破碎效应及部分岩体的加速运动效应的作用下,在远程活动阶段,以高速碎屑流的形式向前运动。
