Under the vertical load, the strength of rock mass is higher when there is only one group of joint and the dip angle is less than 20 or higher than 80; When dip angle is between 20 to 80, the strength of rock mass is much lower, it is smallest when dip angle is about 50, and it is lower when this kind of dip angle is in combination with other angle.

7在铅直向荷载作用下，岩体中只存在一组倾角小于20°或者大于80°时，岩体的强度相对较高；当岩体中存在一组节理的倾角在20°～80°间时，岩体的强度值很小，而且在与其他倾角的节理组合时，岩体的的强度值变化不太大，特别是当节理倾角为50°左右的时候，岩体的强度相对最低。
