摘　　要：从位移法创建者的思维角度出发,依据解的唯一性原理和局部作用原理,再现《结构力学》位移法的创建过程,揭示位移法物理本质;给出形常数在梁结构中对应的直接描述,指出载常数作为结点位移驱动力的物理本质;形常数与载常数构建的平衡方程本质上可以看作阻尼力与驱动力的平衡.采用高观点方式剖析位移法,使《结构力学》位移法蕴含的物理本质得以展示.From the perspective of the creator of displacement method,based on the advanced standpoint of uniqueness principle of solution and local action principle,the creation process of displacement method of structural mechanics was reproduced,and the physical essence of displacement method was revealed.The direct description corresponding to the shape constant in the beam structure was presented,and the physical essence of load constant was pointed out as the driving force of node displacement.The balance equation constituted by shape constant and load constant can be regarded as the balance between the damping force and the driving force in essence.From the advanced standpoint,the displacement method was analyzed,and as a result,the physical essence contained in the displacement method in“Structural Mechanics”was displayed.
