bottom shear meaning in English

底部剪力

The interfacial shear stress is a constant proportion of the bottom shear .
交界面的剪力与底部剪力之比是常数。
In calculation , the bottom shear stress under the effect of waves and currents is supplied by the wave - current bottom boundary layer model
计算中的底部剪切应力由波流边界层模型给出波?流共同作用下的形式。
Shear wall will bear mostly part of horizontal force . in this case , it can satisfy the limitation of displacement , and can be insure that the bottom shear force , natural vibration period of structure and the displacement curve can be novel . furthermore , it can supply good base for proceeding design
在合理的布置下，剪力墙承担大部分水平力，使结构满足侧移限值，并使结构的底部剪力，自振周期及侧移曲线不发生异常，并为以后的工作打下良好的基础。
Excellent correlation exists between the distribution of bottom shear stress and that of sediment types . low shear stress occurs in the central mud area ; where only fine - grained sediment can be imported by weak tidal currents . once settled into the bed , it is difficult for set the sediment into motion
中部泥区为应力低值区所在，水动力弱的中部泥区只能接受弱水动力带来的细颗粒物质，而且这些细颗粒物质一旦沉积下来，便难以再悬浮搬运走，说明中部泥区是连续沉积细颗粒物质沉积区。
