一、前言由于水电、水运工程体积大且结构复杂,大多属于三向应力状态。因此,对结构物只进行平面光弹性应力分析试验,已不能很好地满足工程需要,这就要求我们对所研究的结构物进行三向光弹性应力分析的模型试验。
I. INTRODUCTION Because of the large volume and complex structure of hydropower and water transport projects, most of them belong to the triaxial stress state. Therefore, only conducting the planar photoelastic stress analysis test on the structure can not meet the engineering requirements well. This requires us to carry out a three-dimensional photoelastic stress analysis model test on the studied structure.
