本文通过液化定义引入了视液化角的概念。由此推导出适用于任意固结应力比状态下的一系列砂土振动液化理论判据,解决了在不同仪器中、不同初始固结应力比条件下所做试验数据的归一化处理问题。据此,可以用归一化试验曲线计算、判断复杂应力状态下的液化问题,而不须要了解单元土体中孔隙水压力的变化过程。
This article introduces the concept of viewing liquefaction angles through the definition of liquefaction. Based on this, a series of theoretical criteria for vibration liquefaction of sand subjected to arbitrary consolidation stress ratios were deduced, and the normalized treatment data for test data in different instruments and different initial consolidation stress ratios was solved. Based on this, the normalized experimental curves can be used to calculate and determine the liquefaction problems under complex stress conditions without having to understand the process of pore water pressure change in unit soils.
