The degree of consolidation is an important parameter to evaluate the stability and consolidation effect of soft soil foundation. The degree of consolidation calculated by deformation often overestimates the actual degree of consolidation of soil, resulting in a large post construction settlement. To accurately reflect the actual consolidation degree of soil, based on Terzaghi’s consolidation theory, this paper considers that the deformation amount to soil is equal to the volume of water discharged from the soil pores, and theoretically deduces the calculation method of soil consolidation degree with water content. The one-dimensional consolidation test was carried out by improving the test instrument. The results show that the degree of consolidation calculated by water content is smaller than that calculated by deformation in the same time. The pore pressure is calculated by inversion of the consolidation coefficient, which is close to the value of the pore pressure monitored by the test. It is found that there is a linear relationship between pore ratio and pore pressure (u). When the pressure is large, the e-lgu curve is approximately linear, and its slope can be used as an indicator to evaluate the difficulty of pore pressure dissipation. The research results have a certain theoretical value for revealing the consolidation change and development of soft clay.

固结度是评估软土地基的稳定性和固结效果的重要参数。通过变形计算的固结度通常会高估土壤的实际固结度，从而导致大量的施工后沉降。为了准确反映土壤的实际固结度，基于Terzaghi固结理论，认为土壤变形量等于从土壤孔隙中排出的水量，并从理论上推导了水固结度的计算方法。内容。一维固结测试是通过改进测试仪器进行的。结果表明，含水率计算的固结度小于变形率计算的固结度。孔隙压力是通过将固结系数取反来计算的，该系数接近于测试监测的孔隙压力的值。发现孔隙比和孔隙压力之间存在线性关系（你）。当压力较大时，e-lgu曲线近似为线性，其斜率可以用作评估孔隙压力消散难度的指标。研究结果对于揭示软黏土的固结变化和发展具有一定的理论价值。
