本文通过实验研究和理论分析探讨了变弹模光弹模拟中层面温度约束应力的产生机理及其发展过程,以及层面应力约束与应变约束的一致性,表明了层面两侧最终冻结下来的约束应力均为拉应力。这对进一步消除岩体结构工程的变弹模光弹模拟中层面温度约束效应带来的影响具有重要意义。 In this paper, experimental research and theoretical analysis are used to investigate the mechanism and development process of the temperature constrained stress in the variable-elastic model photoelastic simulation, and the consistency between the stress constrains and the strain constrains on the surface, and the confined stress finally frozen on both sides of the layer. Are tensile stress. This is of great significance to further eliminate the influence of the temperature confinement effect on the surface of the variable elastic model photoelastic simulation of rock mass structure engineering.
