Abstract
In the karst development area,the phenomenon of slurry leakage and hole collapse often occurs in the construction of bridge bored pile,which brings trouble to the construction.In order to reduce the impact on the surrounding complex environment and ensure the smooth progress of the project,this paper takes Baihua Bridge as an example to analyze the construction technology of full casing follow-up super-long pile foundation in karst area.The successful application of this construction technology has achieved certain social and economic benefits,which can provide guidance for similar projects in the future.
