Each virtual simple shear mechanism is simulated by boundary surface plasticity model in the virtual stress and strain space 其中最明顯的是位于與實(shí)際單剪方向一致的虛擬單剪機(jī)構(gòu)。
The innovation of multiple mechanism boundary surface plasticity model is that the effect of rotation of principal stress axial directions and large shear displacement of sand in the earthquake induced liquefaction are taken into account at the same time in the model 獨(dú)到之處在于所建立的多機(jī)構(gòu)邊界面塑性模型能夠同時(shí)考慮土體在復(fù)雜荷載作用下主應(yīng)力軸旋轉(zhuǎn)的影響和砂土地震液化時(shí)剪切大位移特性。
