Probability distribution of shear strength parameters, such as cohesion and internal friction angle in sliding zone, has great influence upon reliability of landslides. So it is necessary to study the probability distribution of strength parameters. 27 landslides, whose physical components of sliding zone are similar to Wanzhou city of Three Gorges Reservoir zone, were chosen, 198*8 statistical data of test values of shear strength parameters in sliding zone were collected, hypothetical tests of probability distribution of shear strength parameters in sliding zone were tested by χ2 test and K-S test. Test results show that single test method to determine probability...
