Abstract
Earthquake-induced liquefaction causes extensive damage to infrastructure. Soil liquefaction-induced effects can account for a significant proportion of damage such as the settlement of existing buildings on liquefiable soils. The influence of structures on the behavior of liquefiable soil is complex. In this paper, the effect of bearing pressure on liquefaction-induced settlement in layered soils was studied. Two 1 g shaking table tests, with different model buildings and bearing pressures, were conducted to establish the ultimate settlement of different structures in liquefiable layered soils. The results showed that as expected the settlement of the heavier building was larger than that of the lighter one. However, the settlement ratio of two buildings was smaller than the bearing pressure ratio. This study will be used as a benchmark for further testing on improving performance through the use of soil reinforcement methods.
