Study on simulation test technology of rock landslide pregnant and sliding mechanism

The pregnant and sliding mechanism of rock landslides was firstly obtained, comparative analysis of modern typical rock landslides information. Then, the failure mechanism of rock landslides was simulated selected a typical rocky bedding landslide as prototype, which damaged mainly by goundwater pressure. The test was to maintain the true latent slip surface and seize the main factors causing the landslide. Major stress magnitude, direction and distribution was basically the same with the prototype in the test. Finally, the prototype landslide hydraulic start critical value was calculated, in accordance with the easily slip over dip slope stability model and its hydraulic start value formula. The rock mechanics parameters and structural parameters of the prototype rock landslide was obtained from the inversion analysis. The simulation test results show that the experimental critical values was coincide with the theoretical critical values, and verify the correctness of the test method.
