Abstract
In response to the stability requirements of construction engineering foundations,taking deep and muddy formations as the prerequi-site,this study focuses on the influence of earthwork excavation on the deviation of pipe piles the corresponding treatment measures.The devia-tion of pipe piles in a certain construction project is summarized,and the impact of earthwork excavation on the deviation of pipe piles is ana-lyzed.Preventive and corrective reinforcement measures such as optimizing excavation methods,setting construction cushion layers,and filling the core of pipe piles are proposed.The research results show that the ultimate bearing capacity of three Class III piles and three Class II piles sampled is 1 730～1 920 kN,and the deviation rate is below 0.5%,which can meet the stability requirements of building foundations.关键词
