摘要: 在Ｂｉｏｔ理论基础上，研究了含单一圆井的饱和多孔地层中，以定流量方式开采时的流固耦合问题。提出了一种解耦方法，求出了耦合的孔隙压力分布和介质应力的解析解。实例计算表明，耦合与非耦合之间的差别是明显的。

Abstract: On the basis of Biot′s theory, a fluid-solid coupling problem in the case that liquid mineral, depositing in saturated porous stratum, is extracted at fixed flux is discussed. First, a decoupled method is proposed, then,the coupling pore pressure distribution and the coupling stresses, strains and displacements of porous stratum are obtained analytically. The computation of practical example indicates that there is obvious difference between the results obtained by coupling and non coupling analyses
