| 摘 要： | 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。

| Abstract: | This paper investigates the occurrence mechanism and developing process of temperature restraint stresses on the layer-face of phototelastic model, as well as the consistence between stress restraint and strain restraint with experimental studies and theoretical analysis. It showed that the restraint stresses frot ventually on both sides of the layer-face are all tensile stresses. All these results arc great importance to eliminate the influence of restraint stresses on photoelastic modelling with variable elastic modulus for soil and rock structures. |
