1) compressive load
压荷载
1.
The effect of sustained uniaxial compressive load on the permeability of concrete was studied by a load-permeation testing device with pressed spring loads.
用以受压弹簧为荷载的压力渗透实验装置研究了持续单向压荷载作用对混凝土的水渗透性的影响。
2) inclined press load
偏压荷载
1.
The(results) show that micro-expansion would occur when titled banded mudstone encountering water,which would result in higher intensity inclined press load on arch lumbus of the supporting structure.
研究结果表明,倾斜层状泥岩遇水产生微膨胀,在支护结构拱腰形成一个高集度的偏压荷载,且随着时间推移荷载值逐渐增大,支护结构达到屈服后,在开裂断面处形成一个塑性铰,致使支护结构变形较大但仍然保持稳定;同时,在隧道拱腰垂直倾斜岩层面安设加密加长锚管,使偏压荷载有效转移,充分调动围岩本身的自承能力,有利于整个支护结构的安全。
3) tension-compression load
拔压荷载
4) negative pressure
负压荷载
5) wind load
风压荷载
1.

通过对屏蔽门样机施加等效风压荷载和人群挤压荷载,模拟屏蔽门受荷载作用下的不利工况。
6) preloading
预压荷载
1.
Based on the equal strain consolidation model of vertical drains,the partial differential equations of the consolidation by sand drain ground were obtained,in which the influences such as the additional stress non-uniform distribution along depth with time-dependent preloading,and the well resistance and the smear action are taken into consideration.

补充资料：冲击波超压与动压
[解释]： 核爆炸产生的高温、高压火球膨胀，在周围介质中形成连续向外传播的压力脉冲（或冲击波），冲击波阵面传播到空间某点时，超过周围环境大器的压力称超压；空气粒子高速随波阵面运动产生的冲击压力称动压。超压和动压都以帕斯卡（Ｐａ）为主单位。超压随时间的变化取决于爆炸威力、距爆点的距离和爆心周围的介质情况。特定地点的峰值超压一般出现在冲击波阵面到达该点的瞬间，超压在该点的持续时间称为正压作用时间。尔后，该点的压力下降到低于周围压力，称为负压，再逐渐回升到周围压力值。对人员的直接冲击伤，超压为２０—２９千帕可引器轻度伤；２９—５９千帕可导致中度伤；５９—９８千帕可造成重度伤；大于９８千帕可造成极重度伤。动压为１０—２０千帕可造成中度伤；２０—３９千帕可造成重度伤；大于３９千帕可造成极重度伤。动压的推动、抛掷和超压的挤压会造成物体变形和毁坏。
