Overview

Randomized trial investigates bearing capacity of prestressed concrete cylinder pipe, suggesting temperature significantly impacts performance.

Key Points

  • This study explores how temperature affects the bearing characteristics of prestressed concrete cylinder pipe (PCCP) during its lifecycle.
  • Focused on a DN3200 embedded prestressed concrete cylinder pipe (PCCPE) as the research object.
  • Developed a hydration degree calculation model considering temperature and concrete age.
  • Conducted a full lifecycle simulation from production to operation.
  • Stress variation analysis at the concrete core invert is the safest method for determining PCCP bearing capacity.
  • Higher construction temperatures correlate with lower prestress and increased stress difference in the concrete core.
  • PCCP bearing capacity is significantly reduced under varying construction temperatures compared to ideal conditions.
