Abstract: Combined with engineering geological conditions of bridge foundation slope, deformation and failure process on the condition of natural state and loading is simulated and analyzed by floor-friction test method based on similarity principle qualitatively. The test results indicate that the rock masses of slopes at left and right banks are in stable state under the condition of natural state; under the condition of loading rock mass in left bank is in stable state; but the scattered earth-body in right bank is unstable; so that the right bank slope is in unstable state. A measure is suggested by pre-reinforcement or changing the location of bridge pier.

Key words: bank slope, floor-friction experiment, similarity principle, deformation and failure mechanism
