| Abstract: | In general,the top of the pile foundation needs to be built-in with the upper structure for the beam-slab piled wharf structure.The traditional single pile integrity testing method can＇t satisfy the requirement of the pile foundation integrity non-destructive testing.By summarizing the research deliverables of the pile foundation testing in China and abroad,the improvement of low-strain reflected wave method and dynamic testing are introduced,which includes mainly double-speed method,transverse wave method,ultra-vibration wave method and longitudinal resistance profile analysis method.It is analyzed and discussed the feasibility of applying high-strain technology in the pile foundation integrity testing of beam-slab piled wharf as well as the advantages of high and low strain technologies which are applied comprehensively in the pile foundation integrity testing. |
