【摘要】 本文通过在动三轴仪上增加模拟初始动水压力条件的控制装置,针对不同的初始渗水条件进行大量的动力三轴试验,探讨不同初始渗水条件(包括动水孔压和渗水坡降)对饱和砂土动力特性的影响,提出“渗透力作用的动力复活效应”的新概念和研究渗水动力效应的必要性。更多还原

【Abstract】 A series of dynamic triaxial tests under the condition of different initial seepage are made, and then the effect of initial seepage (in-cluding the pore water pressure due to water flow and the percolation gradient) on dynamic property of saturated sand is explored on the basisof these testing data by adding a controlling device to the dynamic triaxial instrument,which can model the initial condition of water flow,andconsequently a new concept of the reviving effect of seepage forces is proposed and the need to research the effect of seepage on dynamic proper-ty is pinpointed.更多还原
