斜拉桥力学综合测试实验开发与实践

Development and practice of mechanical comprehensive testing experiment of cable-stayed bridge

斜拉桥的力学分析属于典型工程实际问题,据此开发综合性实验有助于培养大学生实践创新能力。以河南省王楼(省界)至兰考高速公路第二合同段斜拉桥为原型,依据相似原理和量纲分析法获得模型相似参数,建立斜拉桥模型、开发了斜拉桥力学综合测试实验。该实验聚焦大学生实践创新能力的培养,融合材料力学理论与实验测试方法,涵盖了"工程问题-力学建模-理论计算-力学测试-结构优化"的重要环节,实现了工程实际与力学理论的有效结合,在力学实验教学实践中取得了良好效果。

Mechanical analysis of cable-stayed bridges is a typical engineering problem.Developing a comprehensive experiment based on this is helpful to cultivate college students’practical and innovative ability.By taking the cable-stayed bridge at the Wanglou(provincial boundary)to Lankao expressway in Henan province as the prototype,the model similarity parameters are obtained by the dimensional analysis method and according to the similarity principle.The cable-stayed bridge model is established,and the mechanical comprehensive testing experiment of the cable-stayed bridge is developed.This experiment focuses on the cultivation of college students’practical and innovative ability,integrates the theory of material mechanics and experimental testing methods,covers the important links of“Engineering problem-mechanical modeling-theoretical calculation-mechanical test-structural optimization”,realizes the effective combination of engineering practice with mechanical theory and has achieved good results in the practice of mechanical experimental teaching.
