Research on temperature control measures for Jiangkou arch dam

The authors simulated the temperature field and stress field of riverbed monoliths and No6 abutment monolith in Jiangkou arch dam during the construction process by using SimuDam software and SAPTS software, which include a 2D FEM and a 3D FEM and were developed by IWHR. The design institute and the construction company of the project provided the actual meteorological data and data of construction material, foundation rock and dam construction schedule, etc. The simulation results showed that the thermal stress in the riverbed monoliths was small and no special temperature control measure would be needed; but for abutment monoliths, the thermal stress was large and special temperature control measure must be considered. According to the results, the design institute and construction company adopted appropriate temperature control measures and achieved good results in engineering practice.
