等应变条件下的双层理想井地基固结理论

本文建立了Ｂａｒｒｏｎ等应变条件下的双层理想地基固结理论，并为些编制了微机程序、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、井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。

Consolidation theory of donble-layercd ground with vertical ideal drains under equal strain condition

theory is developed for the consolidation of a double-layered ground With vertical ideal drains under Barron's equal strain condition. Several examples have been analyzed and a set of diagrams prepared for practical use. Based on the analysis and the diagrams, the coneolidation behaviour of the ground is discarded. It can be shown.that either an increase in the horizontal coefficient of consolidation of a layer or an increase in the ratio kh2/kh1 accelerates the rate of consolidation of the ground. While an increase in the drain ratio decreases the rate of consolidation, it makes greater the influence of bottom drainage condition on the consolidation behaviour at the same time.
