本文提出一种利用向外径向排水固结试验测定水平向固结系数的方法——固结度对数配合法。它具有较普遍的应用范围,对于所试验的不同土样或不同固结压力～增量比(⊿σct/σ’oct)的情况均可适用,也可适用于多种排水条件,包括由单向固结试验测定竖向固结系数。结合此配合法的验证,利用四个地区的原状饱和软粘土土样在三轴压力仪中探讨压应力和剪应力(排水与否)分别作用下的应力～应变～时间关系。本文为阶段性工作小结,仅提出压应力一种情况的试验结果。
This paper proposes a method to determine the coefficient of horizontal consolidation using the outward radial drainage consolidation test, the logarithmic matching method of consolidation degree. It has a relatively common application range, and can be applied to different soil samples tested or different consolidation pressure-incremental ratios (⊿σct/σ’oct), and can also be applied to a variety of drainage conditions, including from single The consolidation coefficient test determines the vertical consolidation coefficient. Combined with the validation of this coordination method, the stress-strain-time relationship under compressive stress and shear stress (drainage or not) was respectively investigated in a triaxial pressure apparatus using undisturbed saturated soft clay soil samples from four regions. This article is a summary of the phased work and only presents the test results of one case of compressive stress.
