Abstract The bearing capacity of pile foundation is a dynamic system that varies with time and space and is affected by many factors and characterized by uncertainty and limited information data. Thus，the utilization of the existing experiential knowledge is very important in bearing capacity analysis. A new approach to bearing capacity analysis of pile foundation，using the existing experiential knowledge，is presented based on the theories of gray system and analogue. The examples show that the presented method is simple and practical.
