采用英国GDS变围压动三轴系统对温州饱和软粘土分别进行了应力路径斜率η=1/3时不同初始有效固结围压的静力试验和不同应力路径的静力试验,研究了不同条件下温州饱和软粘土的强度特性。试验结果表明,不同初始有效固结围压和不同应力路径的温州饱和软粘土均呈应变硬化规律,且呈非线性;随着初始有效固结围压的增加,土体的强度在增加;应力路径斜率η=1/3时不同初始有效固结围压下,土体所呈现的变化曲线具有相似性。
By using the UK GDS confining pressure moving triaxial system, the static tests of different initial effective consolidation confining pressures and the static tests of different stress paths of Wenzhou saturated soft clay under the slope of η = 1/3 of the stress path were carried out respectively. Strength Characteristics of Saturated Soft Clay in. The test results show that the Wenzhou saturated soft clay with different initial effective consolidation confining pressure and different stress paths shows the law of strain hardening and is nonlinear. With the increase of the initial effective consolidation confining pressure, the strength of soil increases; the stress The curve of the soil presented by the different initial effective consolidation confining pressures is similar when the path slope is η = 1/3.
