| 摘 要： | 从常规试验数据出发,基于改进的Burgers模型对吕家坨矿巷道围岩的应力一应变关系的时间依存性进行了数值模拟计算,得出了与观测相近的结果。通过计算结果和观测结果的对比分析,探讨了该计算模型的合理性和可行性。

| Abstract: | On the basis of conventional test results,an improved Burgers constitutive equation is used to simulate the relation of time dependent stress-strain of the surrounding rock of tunnels in the action of geo-stress in "lvjiatuo".The validity of proposed constitutive relation is confirmed by comparisons of the locale actuarial measurement with results of numerically simulated. |
