Emulation Analysis on the Design of Temperature Control of Power/Sediment Release Tower of the Xiaolangdi Project
Chen Hequn et al. (Hohai University. Nanjing, 210024)
The author has analysed the alternate-section of stage construction process and the emulation data during the operation stage of power/sediment release tower of the Xiaolangdi project, obtained the maximum temperature value and the maximum temperature stress at different parts of the tower in construction stage and thé variations of temperature value and temperature stress of different parts in operational stage and analysed by using time series analysis method of three-dimensionaf finite element. It is shown by the calculation results that the key part of the power tower for temperature control during construction is the thick roof of intake section where the maximum temperature is up to 43.1℃ and the maximum horizontal tensile stress exceeds 3.0 MPa; and the maximum tensile stress in operational stage is in the side wall of the tower.
