Because the shear and the permeability tests are performed as element tests of soils, their obtained results can be used for any theory of analysis. On the other hand, the consolidation test is performed as a model test, and its results are determined through some mother theory of consolidation, such as Terzaghi's theory. Then, theirobtained results are basically available only for the consolidation analysis by their mother theory. This means that each consolidation theory has to have its own test, and is a big obstacle to the progress of consolidation analysis. Therefore, the test for the consolidation analysis should be the element test such as the shear test, and an introduction of the universal consolidation test is indispensable to avoid the barrier.This study proposes the universal consolidation test for the elastic, the elasto-visco-plastic and the elasto-viscous consolidation theories. The constant rate of strain test is chosen as the core of the universal test, and theoretically and experimentally modified to know the creep and the stress relaxation properties of soils.

由于剪切试验和渗透试验是作为土的单元试验进行的，因此其所得结果可用于任何分析理论。另一方面，固结试验是作为模型试验进行的，其结果是通过一些固结的母理论，如Terzaghi的理论来确定的。因此，他们得到的结果基本上只能用他们的母理论进行固结分析。这意味着每一种固结理论都必须有自己的检验，这是固结分析进展的一大障碍。因此，固结分析的试验应是剪切试验等单元试验，引入通用固结试验是避免障碍的必要条件。本文提出了弹性、弹粘塑性和弹粘粘固结理论的通用固结试验。采用恒应变速率试验作为通用试验的核心，对其进行理论和实验修正，以了解土体的蠕变和应力松弛特性。
