垂直应力 meaning in Chinese

perpendicular stress
vertical stress

With the decrease of the coal thickness , the stress in coal and rock will increase , while the harder the coal is , the greater the vertical stress in coal and rock will be , resulting man increase of risk of rock burst
随着煤层厚度的减小，在煤岩体中产生的应力集中将增大；随着煤层硬度的增加，煤岩体中的最大垂直应力也将增大，从而也增加了冲击危险性。
Since the vertical stress distribution of coal and rock can reflect the risk of rock burst , the influence of hardness and thickness of coal seams with a hard roof and a hard floor on the vertical stress distribution of coal and rock was simulated
摘要在坚硬顶板和底板的“两硬”条件下，对不同煤层厚度和硬度对煤岩体中的垂直应力分布的影响，也即反映了对煤岩体中发生冲击矿压危险性的影响进行了模拟。
When the effect of intermediate principal stress was considered in different degrees , the dimensions and shapes of surrounding rock mass is rather different , and this phenomenon will be more obvious with the increase of the difference of horizontal stress and vertical stress
当不同程度地考虑中间主应力的影响时，围岩塑性区形状和大小有较大不同，且随水平应力与垂直应力差异性的增大，这种影响趋于明显。
