Influence factors of the bearing capacity of cast-in-situ bored piles under the karst geology condition are studied. Taking the large diameter cast-in-situ bored piles of Yuanshui bride piers in karst region as an engineering example, effects of three influence factors on the bearing capacity of bored piles are analyzed using FEM, which are the buried depth of the karst cave, the rocked-socketed depth of the pile tip, the distance from the cave to the pile. The results show that the deeper the cave, the higher the bearing capacity of the pile and the more embedded in the rock the pile tip , the higher the bearing capacity of the pile, that is, the deepening of the pile tip embedded in the rock can improve the bearing capacity of single pile. The karst cave different distances far away from the pile, the effect of pile friction is basically the same.
