Abstract

Selecting a reasonable pile type and the pile foundation bearing stratum is important to design and construction in the karst area. It is needed to analyze the stress of pile foundation according to different types of karst caves. By numerical simulation, it is found that under the influence of the settlement of the karst cave filling, negative side friction appears in the area of the karst cave. The more the number of karst cave, the more increase the axial force of the pile. The larger the cave width, or the smaller the cave spacing, the smaller the positive side friction in the cave area. The larger the cave width, the more slowly the axial force decline. With the decrease of the cave spacing, the axial force of the pile under the same depth has an increasing trend.
