Experimental study on liquefaction characteristics of saturated sand–silt mixtures

Soft soil layers, such as sand and silt, are prone to seismic liquefaction when exposed to ground shaking induced by earthquakes. Many severe earthquake disasters in history can be attributed to weak ground conditions. While the dynamic behavior of sandy soils and silts has been widely investigated,...
