| 摘 要： | 摩尔圆图解法不仅可以按三个以上方向的应力(变)测量结果绘出主应力(变)方位、大小,以及应力(变)值随方位的变化;在一定条件下,也可以根据其他的物理量测,如声速、视电阻率等反推应力(变)主方向,并可以分析随时间推移的增量变化特征,供前兆分析。在原位测量确定了主应力(变)后,图解不同结构面上的各分量应力状况、该法具有简捷、直观等优点。

| Abstract: | The azimuth and intensity of main stress, and stress-values varying with azimuth can be described according to the measuring results of stress in three directions by Mohr's circle graphic method. Under certain conditions, the major axis of stress can also be deduced from other physical factors such as the velocity of sound, apparent resistivity, etc. And the variational features of increments varying with time may be analysed. After determining the major axis given at the original measuring position, various components of stress at different structrural planes can be explained through diagram. The principal advantages of the method are simple and straightforward. |
