Test Study on Bearing Behaviors of Piles Considering the Influence of Caves

Abstract:

Based on the static load tests and stress tests results of two cases in Karsts area, the bearing behavior of piles were analyzed and compared in this paper, caves in the base of piles not only affect the base resistances, but also affect the frictions of piles. The finite element method was applied to analyze the influence of rocks in the base of piles on bearing capacities of piles, according to the calculated results; the modulus of rocks affects the bearing capacities greatly, bearing capacities increase with the modulus of rocks increasing.
