- Abstract:
- After the completion of pile foundation construction of oxidation ditch in a WWTP, pipeline excavation was carried out on the north side of the oxidation ditch. Since there was no protective measure for pile foundation in pipeline construction, the pile foundation was inclined when the oxidation ditch area was excavated to design elevation. Due to the lack of relevant construction experience and theory for reinforcement of the inclined pile, it was more complicated to deal with pile inclination situation. In this paper, the traditional calculation and finite element software Abaqus were both used to analyze the damage of pile slope. It was finally determined that the small offset pile was reinforced with core, and the large deviation pile was treated with root pile. The test results showed that the treated pile foundation could meet the design requirements, and the monitoring results of the later operation of the oxidation ditch were good. It could provide reference and theoretical research basis for similar project problems in the future.
