Abstract

It is a very complex problem of pile foundation stability evaluation in karst area, which has been gotten more and more attention in the engineering field. There are many factors that affect the mechanical properties of the pile foundation, including the size, quantity and spacing of the karst. In this paper, numerical simulation is carried out, the results show with the cave number increases, pile axial force increases overall. The larger the size of the cave or the smaller the spacing of the cave, the greater the additional axial force of the pile under the same depth. The cave size has the greatest influence on the additional axial force of pile, and the cave spacing has minimum influence.
