Transverse joint aperture is of certain reference value to ensure joint grouting quality and overall safety of high arch dam. A 3D isoparametric joint element model with spherical surface key grooves and finite thickness is used to simulate a transverse joint. A set of program is developed to simulate the transverse joint aperture of Dagangshan high arch(More)
The flow sheet and operation principle of a liquid filling process was briefly discussed, and the dynamic simulation mathematic models of the filling process were developed in detail using the mass balance equations, gas state equations and historical process data. Based on the intelligent process control (IPC) simulation mode, the overall structure and the(More)
This work is a contrastive investigation of numerical simulations to improve the comprehension of thermo-structural coupled phenomena of mass concrete structures during construction. The finite element (FE) analysis of thermo-structural behaviors is used to investigate the applicability of supersulfated cement (SSC) in mass concrete structures. A(More)
