ABSTRACT

In order to identify the liquefaction potential, soil is considered as homogeneous horizontal layers in all previous studies. However, in reality, soil is composed of layers with some irregularities. Therefore, in the present research, the liquefaction potential of two layers of saturated sand is evaluated considering the irregular topography of layers. The effect of different topographies including crown and valley shapes of one, two, and four sine waves has been considered using two-dimensional models subjected to earthquakes. The results indicate that the irregularly embedded topographies play a role in assessing liquefaction, which can be useful in geotechnical earthquake engineering.

摘要

为了确定液化潜力，在所有以前的研究中，土壤被认为是均匀的水平层。然而，实际上，土壤是由不规则的层组成的。因此，在目前的研究中，考虑层的不规则地形来评估两层饱和砂的液化潜力。使用经受地震的二维模型考虑了不同地形的影响，包括一正弦波、二正弦波和四正弦波的冠谷形状。结果表明，不规则嵌入的地形在评估液化方面发挥了作用，这在岩土地震工程中很有用。
