A Case Study Assessing the Liquefaction Hazards of Silt Sediments Based on the Horizontal-to-Vertical Spectral Ratio Method

Silt liquefaction can occur due to the rapid cyclic loading of sediments. This result in loss bearing capacity underlying sediments and damage foundations infrastructure. Therefore, assessing hazards is an important aspect disaster prevention risk assessment geologically unstable areas. The purpose this study assess silt by using horizontal-to-vertical spectral ratio method. Single-station noise recording was carried out northern plain Yellow River Delta, a new method adopted identify fundamental frequency. dynamic parameters silt, such as frequency, amplification, vulnerability index, were used indicators potential. results show that silty soils different areas have stable ranges values Moreover, distribution observations good agreement with geological conditions area, which indicates potential applicability reliability for identifying index inversely related southwestern part area having lower frequency higher meaning greater compared other has great advantages characterizing subsurface be applied hazard assessments large areas, critically terms providing information guidance urban construction planning.
