| 摘 要： | 将渗流力学与弹塑性力学相结合，考虑煤层瓦斯和煤体骨架之间的相互作用，建立了煤层瓦斯运移的数学模型，并给出其数值解。对煤层瓦斯渗流方程和煤体变形场方程分别进行离散，得到其相应的泛函方程，根据有限元法原理推导出其耦合求解方法，最后进行了实例计算。 |

| Abstract: | Based on the integration of seepage mechanics and elastic-plastic mechanics,taking the interaction between coal seams gas and coal mass framework into consideration,a mathematical model of coal seams gas movement was proposed in the paper,and the numerical solution was given at the same time.By discreting the coal seams gas seepage equation and coal mass deformation equation separately,the corresponding functionality equation was obtained.And on the basis of FEM theory,the method of solving the coupling equation was formulated with some examples. |
| Keywords: | fluid-solid-coupling linear elasticity finite element method seepage |
