Abstract：The failure range and the stability of a bedding rock slope are often affected by the construction disturbance. The bedding slope of Huaping at Jinshajiang bridge connecting the Huali highway was studied in the paper. The results of the in-situ survey，geomechanical analysis and simulation revealed the structure and failure mode of the slope. The model test was carried out under the different combinations of abutment and horizontal loadings，and mechanical analysis was performed. The results indicate that critical horizontal load of different schemes vary from 1.89 to 3.15 kN and that relative limit horizontal seismic accelerations vibrate from 0.134 g to 0.208 g. With the exception of working condition of 100 years seismic fortification criterion，other seismic conditions of Huaping bank slope all meet the revised criterion of 0.105 g(50 years)and 0.144 g(100 years). During model test process，sensitivity and stability rank of monitoring datum are surface force and displacement，inner stress and strain. Sensors? cost-benefit ratio ranks are force-measure ring，centigrade indicator，mini soil pressure cell and strain gage.
