Research on Trial Products of Consolidation Experimentation Apparatus by Terzaghi Model

太沙基固结理论已被用于估算粘性土地基的沉降。本固结试验模型是基于粘性土地基的固结理论，并可利用本装置进行固结现象的试验。在上述力学类比中，弹簧代表饱和土的可压缩土骨架，圆柱体中的水代表土壤空隙中的水。旋塞阀开度与渗透性、弹簧压缩性与土壤压缩性相似。土壤的压缩性越强，固结所需的时间就越长;土壤的渗透性越强，所需的时间就越短。

Theory of consolidation expressed by means of the Terzaghi model has been made use of estimates of settlement of clay ground.This experimentation model of soil consolidation is based on the theory of consolidation concerning clay ground, and the consolidation phenomenon can be experimented with using this apparatus.In the mechanical analogy presented above, the spring represents the compressible soil skeleton of a mass of saturated soil, and the water in the cylinder represents the the water in the voids of the soil. The stopcock opening is analogous to the permeability, the compressibility of spring to the compressibility of soil. The more compressible the soil, the long the time required for consolidation; the more permeable the soil, the shorter the time required.
