Abstract: In order to evaluate the use of bored pile for the landslide remediation, the stability of the slope is evaluated by using the Bishop method and considering all the force effects on the factor of safety. In the evaluation, it is assumed that the force among the slides, the direction and the location of the anti slide force are determined so that the analytical model of landslide with the bored piles can be established and then sliding driving force and the factor of safety can therefore be presented. The relationship of factor of safety among the location of the bored piles and magnitude of the sliding driving forces are also discussed in the paper. The numerical results show that the improved Bishop model analysis of the slope stability by the results with the rest of the algorithm is close to show that this method is feasible and applicable. The estimation of sliding driving force and the rest of the algorithm results within 3% error analysis shows that the model in this paper to establish the good accuracy and reasonable design of the bored pile in slope remediation. The central portion of the slope provides an ideal location for the bored pile the stability of the slope, and the factor of safety increases linearly with the resistance.
