饱和土在自然排水条件下随着剪切作用而发生的含水量增大的行为和过程被称为剪切吸水现象。本文发展了一种新的试验方法,成功地再现了从较松到密实状态的饱和砂土在振动液化后的剪切吸水现象,探讨了剪切吸水速率对饱和砂土液化后应力应变关系的影响。试验结果表明,具有相同密度的饱和砂土,其液化后的应力应变关系随剪切吸水速率的不同而呈现出硬化、理想塑性及软化的不同变化。文中给出了判定这些不同的液化后应力应变响应产生的条件 The behavior and process of increasing the water content of saturated soils under shear conditions under natural drainage conditions is called shearing water absorption. In this paper, a new test method has been developed, which successfully reproduces the phenomenon of shear water absorption after liquefaction of saturated sand from a looser to a denser state, and discusses the relation between shear water absorption rate and stress-strain relationship after liquefaction of saturated sand. influences. The experimental results show that the saturated sand with the same density, the liquefaction of the stress-strain relationship with shear rate of water absorption showed different changes in hardening, ideal plasticity and softening. The conditions for determining these different post-liquefaction stress-strain responses are given
