STUDY ON KEY TECHNOLOGY FOR BORED PILE CONSTRUCTION OF BRIDGE UNDER COMPLEX GEOLOGICAL CONDITIONS
Bored piles as the foundation of bridge engineering are greatly affected by complex geological conditions.Complex construction procedures lead to difficulties in construction quality control and frequent engineering accidents.Taking the pile foundation engineering of a highway bridge in Xinjiang as an example,the rationality of bored pile quality was calculated.In addition,the stress distribution and settlement deformation of a single bored pile under different loads were calculated through COMSOL finite element numerical simulation software.Results have shown that this numerical simulation method could effectively simulate the load settlement deformation process of bored pile.The ultimate bearing capacity of piles can be determined in conjunction with actual monitoring results to accelerate construction and reduce engineering risks to some extent.
