Studies on a self-balanced test for typical stratigraphic piles of YIMA Freeway
摘要
Abstract
Pile self-balanced testing method is a novel and effective method for the detection of pile foundation with flexibility to load and unload,without space constraints,and with advantages of large load capacity,short cycle and good economic benefit.In the paper,based on YIMA freeway typical stratigraphic,the self-balanced testing method was used to study the friction pile bearing capacity of pile foundation of Da Ligang Bridge and the regularities of distribution of pile tip resistance and side friction resistance under load conditions at all levels.The results show that the thickness of mud closed to pile has certain effect on side friction resistance.When the thick-ness is enough,the side friction resistance can be reduced by 50 percent.Therefore,it is a major factor that in-fluences the side friction resistance.关键词
