查询词典 radius

本文针对竖井地基的施工扰动效应及固结可靠性做了如下一些工作：首先，考虑土体自重应力对竖井扰动范围的影响，对Vesic圆柱形孔扩张弹塑性理论解进行了修正，采用Mohr-Coulomb屈服准则，得到了弹塑性交界处土体位移、塑性区半径以及最终挤土应力等理论计算公式，修正以后的结果能更好地符合竖井施工的实际情况。

The relation of the surface shape error to f-number and relevant spherical radius was achieved according to the reducing analysis model ignoring the local f-number.

The results are used to analyze the effect of the surface shape error of the rhombic prism on parallelism of the emergent beam. The assignation plan of the surface shape error for each working surface is presented.
