To address these challenges, this paper presents a new and fully probabilistic procedure for regional hazard mapping of liquefaction-induced lateral spread displacement.
To demonstrate the type of lateral spread displacement hazard maps possible, maps corresponding to return periods of 1033 and 2475 years are developed for Utah County, Utah.
An example map-based liquefaction triggering and lateral spread displacement analysis is performed for a representative site near San Diego Bay.
It accounts for uncertainties in the soil properties, seismic loading, and the empirical models for predicting lateral spread displacement using Monte Carlo simulations.
Earthquake-induced liquefaction may result in the lateral spread displacement of soil down gently sloping ground or towards a free-face, causing severe and costly damage to various facilities, bridges, buildings and other critical infrastructure.
New probabilistic reference parameter maps for liquefaction triggering and lateral spread displacement are developed and presented for San Diego, California, and simplified probabilistic equations necessary to use the reference parameter maps are summarized.
