摘　　要：模型物理力学参数测量问题是制约相似模拟技术推广应用的主要因素之一。论文在对平面相似模型应力应变测量技术全面分析的基础上 ,重点分析了用传统测量方法与手段进行三维物理模型内部应力应变测量时遇到的困难与问题 ,阐述了发展光波导应力应变测量技术的重要意义。The problem of physical and mechanical parameter measurement in model is the main factor of restricting extensive application of similar simulation technique. Based on comprehensive analysis of stress-strain measurement techniques in planar similar model, the difficulties and problems confronted in three-dimensional similar model stress-strain measurement with traditional methods are carefully analyzed, and the important meanings of developing waveguide stress-strain measurement technique are discussed in this paper.
