| 摘 要： | 采用岩层的新鲜的不规则岩块（长、宽、高符合一定规格）用点衔仪直接在现场进行测试，所得数据在微机上进行计算及绘图，得到所需的结果。由于点荷载数据符合正态分布规律，采用Ｇｒｕｂｂｓ准则对可疑数据进行取舍，从而代替了人为取舍方法。

| Abstract: | The existing experimental method for testing the rock strength has some shortcomings. Complicated process, complex technology. High expenditure, and without testing on the spot of workplace. The writers put forward a new method: collecting some fresh irregular rock piece from the rock bed, the height, length and width of which are accoring accordance with certiai certain regulation, testing them on a point load apparatus at the workplace directly, and processing the data to find the point load strengh of rock. Because the point load data are conformed to the normal distributiom's law, the Grubbs criterionmay be used to decide which one should be accepted or rijicted of manual instead of manual method commonly used. Thus ordinary workers can operate the test easily. |
