Influence of Karst Caves on the Pile’s Bearing Characteristics-A Numerical Study

Compared with the amount of research undertaken on vertical-bearing piles in karst areas, there are fewer studies stability horizontal-bearing (e.g., anti-slide and supporting piles), little way theoretical developments. In order to study influence cave front under pile anti slide pile, this designs orthogonal test, carries out numerical simulation by using ABAQUS finite element analysis software, deduces displacement load curve each group piles, then determines lateral ultimate bearing capacity when exists, Through multiple linear regression test parameters such as distance between tip, span height ratio it is concluded that a significant correlation above participation capacity. The results have certain guiding significance for application area.
