1)  Pore pressure
孔隙压
1.

从岩土力学的角度对水库蓄水后坝基和坝体形成渗漏裂缝的机理进行了理论计算和对比,结果表明,大高度蓄水静水压产生的附加应力并不是形成渗漏裂缝的主要因素,而一定高度蓄水引起岩土体内孔隙压升高到极限值才是产生破坏性裂缝、形成渗漏的主要原因。

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。
