Abstract Based on the cutting mechanism，besides the mathematical model for torque and axial force being established，the mathematical model for torque and axial force on the probe，changing with the penetration velocity，the rotary velocity of the probe and the physico-mechanical parameters of rock and soil masses，is also developed by analyzing the forces on cutting edges of probe. In addition，the validity of the mathematical model is proved according to the data from laboratory experiment. The influence factors on the torque and the axial force of probe unit are analyzed；and the theoretical basis of rotary penetration technique，which is made clearly，is that the values of axial force and torque of the probe unit only depend on mechanical property of rock and soil masses when the running mechanical parameters of machine，probe diameter，materials and form of the probe are all the same. Moreover，the axial force of rotary penetration test is compared with that of static cone penetration test to fundamentally explain the reason why rotary penetration test can be applied to rock mass.

Key words： rock mechanics geotechnical engineering investigation static cone penetration rotary penetration
