LIQUEFACTION ANALYSIS OF SATURATED SAND DEPOSITS WITH SILT LAYERS SUBJECT TO 1 AND 2 COMPONENTS OF EARTHQUAKE MOTION
Liquefaction of saturated sand layers has been extensively studied by various researchers. The studies conducted were both experimental and analytical. An important issue identified by the researchers is the simultaneous application of all 3 components of the earthquakes, especially the 2 horizontal components for a better representation of real life cases. In this paper, the behavior of loose medium dense sand deposits with and without a silt interlayer has been presented in figures using LASS III computer code. In these analyses, the focus is on the liquefaction phenomenon which is one of the most important problems occurring in sandy-silty soils during strong ground motions. The presence of less permeable layers, such as silt seams in sandy soils, results in higher excess pore water pressures increasing the risk of liquefaction. The difference between the outcomes of utilizing one or two horizontal components of the earthquake motion is also presented.
