摘　　要：研究了单面排水条件下未打穿竖向排水井地基的固结问题,通过在排水井底面以下土层中设置虚拟排水井,得到了能考虑该土层三维渗流的解析解,这也是迄今与实际情况最接近的未打穿排水井地基固结解。根据所得解编制了计算程序,分析了未打穿竖向排水井地基的固结性状。并基于此解,对现有相关近似计算方法和解作了较完整的比较和讨论。The consolidation of soft soil with partially penetrated vertical drains under single-drainage condition was studied, and an analytical solution was obtained assuming a virtual drain beneath the tip of actual one. This solution took consideration of three-dimensional seepage existed in the soil under vertical drains and thus was the best approach so far to actual situation. Corresponding computer program was developed and the consolidation behavior of soft soil with partially penetrated vertical drains was investigated. Moreover, based on the solution, the relevant approximate methods so far available were compared and discussed.
