roof displacement的意思|示意

Roof Support elevation, the axis displacement and cross-deflection, the measurement made by the record.

屋架支座的标高、线位移、中挠度，经测量做出记录。

It shows that, in displacement-based seismic design, we also should improve the target roof displacement computing method based on the value of r.

这意味着在基于位移的设计中，还应该以R取值为依据，对顶点目标位移的确定方法进行修正。

The numerical results show that the displacement of the overlying strata is nonlinear, and it gets smaller with the increase of the roof height.

数值模拟结果显示上覆岩层的移动是非线性的，上覆岩层的沉降位移随着距离采场顶板的高度增大而减小。
