| Abstract: | Guided with the result of "Study on Simulation of the character of pile foundation in a karst area",a cave roof with thin stratum method was reinforced with compound pile foundation(cast-in-situ pile by hand excavation+spiral jet+steel pipe pile).The whole optimization process of the compound pile foundation design program and the calculation of its bearing capacity have been introduced in details.Practice has proved that this design program can be used for reference in the future. |

| Keywords: | compound pile foundation reinforcement bearing capacity |
