| Abstract: | By the porosity, strength, deformation and permeability of rock masses, it is proved that the properties of rock masses are influenced by stress condition and are the function of spatial position. They have the characteristic of random field. Moreover, the concept of the physical field for engineering rock masses is proposed. To be coinsided with the characteristic of the ‘field’, some traditional working methods in rock engineering should be improved, such as the arrangement for in situ test points and the statistics of test parameters etc.. |

| Keywords: | the property of rock masses the physical field of rock masses ground stress |
