Paper Title:
Loading Behaviors of Superposed Aqueduct Affected by Segregating Layer Between PPCBs and Cast-In Situ RCF
  Abstract

Combined with the structural design of left-shore drainage aqueducts in China South-to-north Water Transfer Project, the structure of cast-in-situ reinforced concrete flume (RCF) with wide and shallow drainage section superposed on longitudinal precast prestressed concrete beams (PPCBs) was drafted. The 3D finite element models were built to study the normal service behaviors of the aqueduct with or without segregating asphalt layer between RCF and PPCBs. The results show that the segregating asphalt layer changes the structural compositions of aqueduct subjecting water loads and results in some effects on loading capacities of the PPCBs and the RCF, such as the larger displacement and tensile stress of PPCBs, the many longitudinal sections of subplate in whole tensile state with larger tensile stresses and the larger vertical tensile stresses at internal surface of sidewall. It provides valuable reference for designing the same kind of aqueduct.
