本文应用非线性数学规划理论,研究了混凝土坝浇筑块基础温差的最优化设计问题。文中从可靠性理论出发,概率地描述设计变量,并以相对初始造价和裂缝后修补费用总和最低为原则,建立规划的目标函数。上述问题的解法,采用改进的复形法,并用网格法进行校核。 In this paper, the nonlinear mathematical programming theory is applied to study the optimal design of the temperature difference of concrete dam foundation. Based on the reliability theory, the paper describes the design variables in a probabilistic manner and establishes the objective function of the planning based on the principle of the lowest initial cost and the lowest total post-crack repair costs. The solution to the above problems, the use of improved complex method, and check with the grid method.
