A Development Study on the Universal test for the One-dimensional Consolidation

由于剪切试验和渗透试验是作为土的单元试验进行的，因此它们所获得的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，其结果是由一些母固结理论，如太沙基理论确定的。所得结果基本上只适用于其母理论的固结分析。这就意味着每种固结理论都必须有自己的检验标准，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，而通用固结试验的引入是必要的，以避免障碍，本研究提出了通用固结试验的弹性，弹粘塑性和弹粘固结理论。本文选择恒应变速率试验作为通用试验的核心，并对其进行理论和试验修正，以了解土的蠕变和应力松弛特性。

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.
