摘　　要：研究了具有半透水边界的竖向排水井地基粘弹性固结问题 ,给出了相应的解析解 ,并根据该解析解通过编程计算 ,探讨了半透水边界及土的粘弹性参数对竖井地基固结过程的影响。In this paper, the problem of viscoelastic consolidation of soft clay ground with vertical drain wells considering semi-permeable boundaries that may result from the defective drainage capacity of both sand cushion and substratum in practical engineering is studied, and the analytical solutions are obtained. Based on these solutions and relevant computations, the influences of semi-permeable boundaries and viscoelastic parameters of soil on the consolidation process are investigated and discussed. It shows that the semi-permeable boundaries affect the consolidation process significantly and the effect is related to many factors such as well resistance. However, if the values of parameters Rv1 and Rv2 which represent the drainage capacity of sand cushion and substratum are large enough, the semi-permeable boundaries can be taken as previous completely.
