在三种压实粘性土的三轴排水试验中,进行若干次卸荷和再加荷循环。本文介绍了测得的卸荷弹性模量值,并与加荷条件下的相应模量值进行比较。研究了卸荷弹性模量随四周压力以及卸荷时的剪应力水平而变化的规律。
In three triaxial drainage tests for compacted clayey soil, several unloading and reloading cycles were performed. This article describes the measured unloading elastic modulus values and compares them with the corresponding modulus values under loading conditions. The law of the change of the unloading elastic modulus with the ambient pressure and the shear stress at the time of unloading was studied.
