Abstract: This paper presents an optimum design method of the concrete anchorage for hot pipeline according to a given thrust force and allowable displacement, and proposes a new shape of the concrete anchorage pier based on theoretical analysis and experimental comparison. A mathmatical model and computer program for determination of anchorage size are established on the basis of optimization theory with the amount of concrete quantity used as objective function and balance of forces, stability against overthrow, adequate strength as constraints. A set of calculated results show that the amount of concrete used for making the anchorage pier designed by the optimization method is significantly less than that designed by the usual method by about 20%～60%.

摘要： 埋地原油热输管线中混凝土固定墩的用量很大,为了节省材耗,研究其优化设计方法十分必要。本文提出按推力和许可位移两个指标对混凝土固定墩进行优化设计的方法,并经过分析和试验推荐了一种燕翅状的新墩形。文中以混凝土用量为目标函数,以受力平衡、抗倾稳定、强度安全等要求为约束条件,研究了确定墩体各边尺寸优化介的数学模型,并开发了成套的计算软件。大量系列例算的结果表明,优化设计的混凝土固定墩比一般设计的混凝土固定墩可以节省材料20%～60%,具有显著的经济效益。
