【Abstract】 Abstract In this paper a non linear programming model of comprehensive optimization of joint closure temperature field and its shape is established. The joint and its closure temperature field parameters are considered as the design variables and the total cost including dam body concreting and its cooling cost as the objective function, the safety and practicability as the constraint condition. The application shows that this model is reasonable and the optimizing effectiveness is remarkable.更多还原
