在上海地区典型饱和软粘土不排水循环三轴试验的基础上,分析了影响软粘土塑性累积变形的主要因素:循环荷载的作用次数,初始静偏应力和循环加载动偏应力。
It was shown that the cumulative plastic strain depended not only on the applied cyclic stress and number of cycles, but also on the initial static deviatoric stress level.
以往的研究大多忽略初始偏应力对软黏土循环软化及动应力-应变关系的影响。
Unfortunately, previous work rarely incorporated the effect of initial deviator stress on cyclic degradation behavior and dynamic stress-strain relationship of soft clay.
当破坏标准选定时,界限累积耗损能量与平均应力、偏应力比及动应力间较好的回归关系。
When the failure criterion is decided, the limit accumulate energy dissipation can be fitted by a formula which includes the average stress, deviator stress ratio and cyclic axial stress.
