摘　　要：就实际工程中荷载逐渐施加情况下的竖向排水井地基粘弹性固结问题进行了研究 ,给出了相应的解析解 ,根据该解 ,通过编程计算 ,探讨了变载下竖井地基粘弹性固结的一般规律。并应用本文提出的理论对工程实例进行了分析。The viscoelasic consolidation by vertical drains under time-dependent loading is studied in the paper.A program based on the solution is developed.The general rules for the consolidation by vertical drains due to variable load are obtained.Influences of parameters and loading time on a consolidation process are investigated.It is shown that the consolidation process is much more effected by the viscoelastic parameters.The longer the loading time the slower the consolidation course.The effect of loading time is decreased with the time increasing.The consolidation degree obtained under the condition of Barron's equal strain is larger than that of the results of Barron's free strain while the conpressibility of the smeared zone of both are in consideration.
