Abstract: A new solution under the non-uniform distribution of initial pore pressure expressed in a unified expression was derived from the equivalent strain governing equation for the consolidation by vertical drain wells on the basis of the Merchant rheological model.The correctness of the proposed solution was verified by comparing with the viscoelastic solution under the uniform distribution of initial pore pressure.The calculation program was coded to analyze the influence of the viscoelastic parameters and the initial pore pressure parameters (described by k and η)on the consolidation characteristics of soil ground with vertical drain wells.The research shows that the increase of k and η will slow down the rate of the consolidation，and increase the average pore pressure at the same depth.The increase of k and η has more significant influence on the average pore pressure of soil ground with vertical drain wells than that on the average degree of consolidation; under the same condition，the change of k makes much more influence on the average degree of consolidation than that on the average pore pressure of soil ground with vertical drain wells.

摘要： 将初始孔压非均布条件用统一表达式表示，采用Merchant模型推导了初始孔压非均布条件下的竖井地基黏弹性解。通过与初始孔压均匀分布条件下 的黏弹性解对比，验证了本文解的正确性。并编制计算程序分别分析黏弹性参数、初始孔压参数对于竖井地基固结特性的影响。研究表明：k及η值的增 大均使固结速率降低，使同等深度的平均孔压增大，且对竖井地基平均孔压的影响较其对平均固结度的影响明显；同样条件下，k值的变化对竖井地基固 结特性的影响更大。
