本文建立了等应变条件下较为完善的打穿软粘土层的砂井地基固结解析理论，该理论较同样条件下现有理论更接近自由应变条件下严密的但极其复杂的解析理论。文中对巴隆（R. A. Barron）理论和汉斯(s．Hansbo)理论作了详细的分析和讨论，阐述了考虑井阻作用时巴隆理论的不合理性和双斯理论的近似性。最后根据本文理论编制了可用于IBM-PC微机的绘图软件，绘制了常用砂井的平均径向固结度-径向固结时间医子等曲线。利用这些曲线，能较方便地进行考虑井阻作用和涂抹作用的砂井地基设计。

本文研究了双层地基一维固嫱问题，给出了荷载随时间任意变化及起始孔压沿深度任意分布情况下双层地基一维固结解答。讨论了双层地基一维固嫱特性，并为双层地基平均周结度的实际计算提供了图表。与均质地基不同，双层地基平均固结度按沉降定义和按平均孔压定义是有区别的。土的厨结系数并不是决定双层地基固结速率的唯一指标。土的压缩性对职层地基固结有重要影响，土越硬，固结越快。

本文建立了Barron等应变条件下的双层理想井地基固结理论，并为此编制了微机程序、绘制了固结计算曲线。文中还论述了理论解中特征根的变化规律，并就土层的水平向固结系数、渗透系数、并径比以及底面排水条件对双层理想井地基固结的影响进行了分析。

In this paper, a fully explicit analytical solution is presented for one-dimensional consolidation of two-layered soils with partially drained boundaries. It can be shown that the available analytical solutions so far developed for one dimensional consolidation of soil are the special cases of the solution presented herein. According to the solution, some diagrams are prepared and the relevant consolidation behavior of layered soils associated with partially drained boundaries is discussed in detail. Furthermore, the applications of the solution are illustrated in an example problem.
