摘要
Abstract
By pre-embedding fiber-optic strain sensors in large-diameter friction piles,the strain distribution on each pile section was measured while executing the static load tests of pile foundation by using slow-speed load method.the distribution of pile internal forces was calculated and the distribution law was studied.To further determine the failure mode and the ultimate load of pile body,a finite element numerical analysis was made based on the field testing results.The related specifications were combined with the finite element analysis to deduce the ultimate bearing capacity of test piles,which provided a reference and experience for the design optimization of similar projects.关键词
