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%.
