| Abstract: | The stochastic medium theory was presented to denote the intensity of ground mass using the deformation of ground mass,and to analyze the principles and the fundamental equations of the stochastic medium theory applied to the slope engineering.The analytical formula on the movement and deformation of the surface and the interior to ground mass resulting from excavating slope engineering were obtained,and the choice of parameters for calculating was discussed.Finally,the reliability of the stochastic medium theory has been confirmed by an example.All the results show that the Mole-Coulomb theorem can not only be treated as the limiting equilibrium analytical method and also be treated as the stress-strain numerical analytical method for the criterion to landslide. |
