| 摘 要： | 光弹实验应力分析是模拟研究地壳构造应力场的有效方法。本文在单一材料光弹应力分析剪应力差法计算模型应力公式的基础上,得出了不同材料的层状光弹模型界面点应力初值计算式,并介绍了这些公式在构造应力场光弹试验分析中的应用。这些计算式对于定性与定量分析地质力学光弹模型的应力分布,进而分析原型应力分布规律,评价其稳定性,具有一定的参考意义。

| Abstract: | Formulas of calculating initial stress on demarcation surface have been established for various photoclastic material
and applied to analysis of tectonic stress field in photoelastic experiment. The results obtained well coincide with reality.
The formulas proposed can be used for qualitative or semiqualitative regional stress field analysis, providing a new ap-
proach to structure stability assessment. |
