对局部的或区域性的构造应力场作平面光弹性模拟分析,国内外早已进行,并广泛地应用在探索地质构造形成及地震规律的研究中。虽然平面的模拟实验是与弹性常数E、v无关的,但是由于问题的复杂性,特别是因为构造力大小未知,实验结果只能反映各处地应力值的相对大小。如果认为地质体(原型用脚标H)和模拟材料(模型用脚标M)为线弹性体,即设
For the local or regional tectonic stress field, the plane photoelastic simulation analysis has been carried out at home and abroad, and has been widely used in the exploration of the formation of geological structure and the study of seismic laws. Although the plane simulations are independent of the elastic constants E, V, the experimental results only reflect the relative magnitude of the stress values everywhere because of the complexity of the problem, especially because of the unknown magnitude of the structural forces. If we think that the geologic body (prototype foot H) and the simulated material (model footer M) are linear elastomers,
