| Pre-stressed Spun Concrete Squared Pile has the Advantage of higher carryingcapacity, high speed of construction, handling and stacking in safety, high qualityof construction, without Slurry mud protection wall during construction time, staticpressure, free of noise pollution and so on. However, due to the advent of time, itlacks the Knowledge of theory or practice, which influences the development ofPre-stressed Spun Concrete Squared Pile. This paper is at the foundation of AnhuiProvince, s local technical specification "Technical specification for pretensionedpre-stressed spun concrete squared pile foundation",on this basis, we discussed thebearing characteristics of Pre-stressed Spun Concrete Squared Pile systematically.What people most concerned about Pile foundation is Load-bearingcharacteristics. in this paper, we tested two Pre-stressed Spun Concrete SquaredPile with different pile diameters, by using of pasting hollow square on thepiles,we can know the relationship of upper load and compression deformation, wealso discussed the bearing characteristics, load-settlement relationship, transfermechanism of load and the distribution of pile friction and tip resistance throughexperimental data.By means of field tests, we found suitable methods apply to studying thebearing characteristics of Pre-stressed Spun Concrete Squared Pile, and we alsoprovide reference for how to use Pre-stressed Spun Concrete Squared Pile in thisregion. |
