The paper expounds some issues in arch dam design from engineering practice, including the optimization of arch dam body shape， arch dam curvature, cement breed， closed arch temperature， strain－ controlled working regime， stability analysis against sliding for dam foundation and soft intercalated layer treatment.

In combination with the Heigou Bridge Project in inner Mongolia, the methods of construction stress control are discussed in this paper.

Combined with practical instance, this paper throws lights on the application of the working conditions involved low temeprature and low stress in the design, providing inspiration for the lay-out of the liquied chlorine pressure receptacle.
