摘要

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 X~2 test and K-S test. Test results show that single test method to determine probability distribution of shear strength parameters in sliding zone has great limitations. For instance, probability distribution of strength parameters cannot be determined in case several hypothesis of probability distribution all can be accepted or rejected. It is necessary to determine the probability distribution of shear strength parameters in sliding zone by using multiple test methods. In connection with 27 landslides data of controlling landslides for the third plan in Wanzhou city of Three Gorges reservoir zone, multiple test methods of determining probability distribution of shear strength parameters in sliding zone are developed in this paper.
