Study on Disjoint Floating in Prefabricated Piles Construction and Disposal Measures

In this paper,the influence of pile construction on the surrounding environment is introduced,combined with an engineering example,the influence of the section of precast piles with multiple sections on the engineering is analyzed.Due to the limited sampling rate,the static load test may not fully reflect the overall bearing capacity of the pile.In the first part,the low strain method is used to carry out a certain proportion of the sampling to the engineering piles,the high strain and the static load test results which proves the conclusion of the low strain.According to the analysis of the reasons for the Ⅲ piles found in the sampling,it is pointed out that there is a gap between the precast piles in the project.After repressing,the static load method is used to verify the test results,and the results meet the original design requirements.Settlement observation of buildings shows that:the maximum cumulative settlement is 6.54 mm,and the settlement is uniform and stable.
