结构力学位移法基本思想表述及课程思政映射与融入

Basic Cognition of Displacement Methodof Structural Mechanics and the Mapping and Integration of CurriculumIdeology and Politics

位移法是求解超静定结构的基本方法,是《结构力学》课程的核心内容。针对位移法知识点繁杂、概念多、记忆参数多、理解难度大的现状,作者根据教学实践,基于能量平衡视角阐述位移法基本思想,厘清位移法解题思路,展示了在荷载及非荷载条件下位移法解题的步骤。针对力学课程思政存在“两张皮”和思政素材受局限的问题,作者建议将力学方法与哲学思想相联系,提出“力学知识点→哲学思想→思政素材→思想引导”的课程思政模式,扩大了思政素材选取外沿,实现了力学课程思政的“软融入”,并以位移法为例展示了课程思政映射与融入的路径和做法。

Displacement method is an essential approach for solving statically indeterminate structures,and is the core content of the course Structural Mechanics.In view of the complex knowledge points,multiple concepts,multiple memory parameters and difficult understanding of displacement method,this paper,based on the energy balance perspective,expounds the basic concept of displacement method,clarifies the problem-solving ideas of displacement method,and demonstrates the problemsolving steps of displacement meth-od under load and non-load conditions.Aiming at the problemof the separation of theoretical teaching and curriculumideology and poli-tics,and the problem of the limitation of ideological and political materials in the course of mechanics,this paper proposes to connect the displacement method with philosophical thoughts,and puts forward the ideological and political model of“mechanical knowledge points→philosophical thoughts→ideological and political material→ideological guidance”.This mode expands the selection of ideol-ogical and political materials,realizes the“soft integration”of the ideological and political aspects of the mechanics course,and takes the displacement method as an example to demonstrate the mapping and integration path and methods of curriculum ideological and political.
