SELECTION AND OPTIMIZATION OF THE SITE OF BRIDGE PILED FOUNDATION ON THE LAYERED ROCK SLOPE

How to choose a reasonable bridge pile in slope Valley, has important significance for saving the construction cost. In this paper combined with a large highway bridge pile position selection problem, under full analysis of the engineering geological conditions of the bridge site and take the limit equilibrium method, finite element method slope stability analysis method, according to the three conditions, the stability of different design schemes of bridge pile slope are calculated and analyzed. According to the slope stability of different bridge pile analysis results, determine the optimal design of the bridge pile.
