| 摘 要： | 本文用连续介质力学的理论分析了岩石屈服前的性状,导出了岩石介质的非线性弹性的本构方程并与试验资料进行了比较,结果令人满意。进而用非线性弹性取代一般帽盖模型中关于弹性区的线弹性假设,给山了一个新的非线性弹性-塑性硬化帽盖模型。

| Abstract: | In this papar, the rock behavior before yielding is analyzed by using the theories of continuum mechanics. The nonlinearly elastic constitutive equation of rock medium is derived and compared satisfactorily with the available experimental data. Moreover, the substitution of linearly elastic hypothesis used in the conventional cap model with the nonlinearly elastic one leads to develop a new nonlinearly elastic-hardening plastic cap model as presented herein. |
