Abstract： In this paper， the feasibility of using end-bearing rigid pile composite foundation is analyzed based on the current code， relevant research and engineering examples. Through the calculation and analysis of the bearing capacity and deformation of the end-bearing rigid pile composite foundation in a karst area， the design process of this kind of engineering is introduced. The obtained characteristic value of bearing capacity meets the requirements， and also provides a reference for the same type of project.

Keywords： karst area; end bearing type; rigid pile; composite foundation; bearing capacity
