explosion velocity meaning in English
爆速
Examples
- ( 三 ) under the dynamic load of the explosion , the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0 . 3hz , the acceleration of the slopes top gets the maximum ; so 0 . 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform , when the relative altitude is up to 45m , the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m , the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration , at the top of the slope , the acceleration of horizon become larger and larger ; at the middle part of the slope , it becomes smaller ; ( 4 ) when the explosion velocity of is much little , the shallow part destruction is the primary deformation of the slope
(三)采用模态叠加法针对爆破动力作用,进行边坡的动力响应分析,得出了以下结论: ( 1 )振动频率为0 . 3hz时,坡面顶部水平向加速度峰值最大;综合考虑,可认为该边坡的自振频率为0 . 3hz左右; ( 2 )地形对爆破地振动存在放大作用,研究剖面的坡面,水平向加速度及位移在地形相对高差45米左右最大,而后随相对高差的增高而减小,相对高差为100米时,水平向位移及加速度绝对值均大于坡脚; ( 3 )强迫振动段,水平向加速度值随时间变化的规律为:坡顶节点总的变化趋势是越来越大,而坡体中部节点的变化趋势是越来越小; ( 4 )当爆破振速较小时,变形破坏的形式表现为坡顶表面滑塌型。
