| 摘 要： | 把初始地应力及一定形状洞室的开挖作为已知输入，洞周不同点在不同时刻的位移实测值作为已知的输出，多次使用最小二乘法及优化技术，建立了一套岩体流变本构模型辨识的理论和方法，并编制了计算机程序，对具有流变性态的任何地下工程岩体，可方便地确定其流变本构模型．

| Abstract: | With the initial ground stress and excavation of adit with specific shape as known input and the displacement measurements of the adit periphery at different points and different time as known output, the theory and method of rheological constitutive model of rock mass were built by using least square method and optimum technology again and again. The calculating program was compiled. The rheological constitutive model of any underground engineering rock mass with rheological property can be determined conveniently by using the present method. |
