An effective stress calculation formula for coal containing gas is proposed coupling with the swelling stress of gas adsorption in the effective stress principle for porous media. 摘要首先在多孔介质的有效应力原理中引入瓦斯吸附的膨胀应力，推导出了适用于含瓦斯煤岩的有效应力计算公式。
It is indicated that creep constitutive relation of gas-comtaining coal can be expressed by the nonlinear viscoelasto-plastic creep model correctly. 实验结果与该模型的理论值吻合较好，表明河海模型能正确描述含瓦斯煤的蠕变本构特性。
