A series of on-site point load tests for the Middle Proterozoic Wudangshan Group (Pt2wd) schist are carried out based on the probability theory and statistics
to determine the grouping interval of the point load strength (vertical rock) of the completely
strongly and moderately weathered (Pt2wd) schist. The point load tests at different levels along the schist direction are carried out; the correlation of point load strength between parallel to the rock and vertical rock is analyzed; and the anisotropy index Ia of the schist is determined; combined with the results of uniaxial compressive strength test indoor
an empirical correlation relationship of the point load strength IS and uniaxial compressive strength Rc of Wudang Group schist is given.
