relative altitude meaning in English
相对高度
Examples
- But this well was an inclined well . this is one point . this well was near to the top of holy spring mountain , considering relative altitude , its 150meters higher than koutou , but it has never dried
此井有两处怪异：正常水井的井壁必须垂直，利于提水，而此井壁却整体向南倾斜，这是一怪此井接近圣泉山山顶，按相对高度，几乎等于凭高悬在口头村上空150米处，而井水常年流溢，从不干枯，这是二怪。 - ( 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。
