Stress distribution in this arch dam under water level of 1090 m (MPa): (a) the first principal stress in upstream surface under measured high temperature; (b) the first principal stress in downstream surface under measured high temperature; (c) the third principal stress in upstream surface under measured high temperature; (d) the third principal stress in downstream surface under measured high temperature; (e) the first principal stress in upstream surface under measured low temperature; (f) the first principal stress in downstream surface under measured low temperature; (g) the third principal stress in upstream surface under measured low temperature; (h) the third principal stress in downstream surface under measured low temperature.
