Optimization and Sensitivity Analysis on Estimated Parameters for Slope Engineering

Abstract:

The site is located at mileage 50K +650, Tai-174 Road near the mountain slopes. The vertical range is about 150m and the area is 30000 m2. The present study adopted the finite element method program "the PLAXIS 8.2” to analysis. The contents include: (1) To analysis the slope stability on condition that to increase groundwater level is the antecedent of building a function which is the least squares difference between changing slope value and calculated value. Then this study explored the effect of the soil parameter values in different soil layer, parameter sensitivity, to the objective function. Simultaneously, this study sought the optimal parameters of the finite element model in this site in order to be the post-conditions analysis; (2) In order to prove the correctness, this study analyses and compared the data from sliding surface and tilt tube.
