边坡稳定性的动力影响因素分析
|
摘要
边坡在地震或爆破振动等动力作用下的稳定性问题是目前研究的较热门问题.本文在总结影响边坡稳定性因素基础上,给出了描述震动效应的参数.地震或爆破振动的动力作用均可引起边坡的失稳,边坡的高度、形状、结构及地形特点也是决定边坡是否在动力作用下破坏的重要因素.此外,震源及质点的振动速度、振幅等也是判定边坡的失稳依据.
The stability of slopes under dynamic forces like earthquake and blasting is now a hot issue attracting researchers' attention.This paper gives out parameters describing shocking effect based on the study of factors influencing the stability of slopes.Earthquake or blasting vibration can destroy slope stability.The height,shape,structure of the slopes and characteristics of the terrain are the important factors deciding the damage and destruction of the slopes.In addition,the location of the epicenter and the velocity and amplitude of the particles also contribute to the stability failure of the slopes.
