摘要
This paper analyzes the formation mechanism of composite foundation in the karst area, at the same time studies the strengthening mechanism of the CFG pile composite foundation by using the finite element software Plaxis, and discusses some problems in the application of CFG pile composite foundation by integrating correlative data, it was suggested to use the weighted average fsk of subgrade bearing capacity characteristic value within the range of pile length to calculate the bearing capacity of composite foundation fspk.
