Earthquake-Induced Deformation Analysis Of A Bridge Approach Embankment In Missouri, W. Liu, Ronaldo Luna, Richard Wesley Stephenson, S. Wang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Earthquake-Induced Deformations for a Bridge Approach Earth Embankment Are Predicted using a Calibrated Numerical Model. the Constitutive Soil Model is a Modified Hyperbolic Model that Uses Masing Rules and Incremental Pore Pressure Relations. the Model Was Calibrated using Both Laboratory and Field Data. a Shaking Table Physical Model Was Used to Verify the Numerical Simulation. Additionally, the Upper San Fernando Dam Was Modeled to Reproduce the Deformations in the 1971 Earthquake. the Subsurface and Embankment Soil Conditions Were Characterized using Field and Laboratory Methods. the Model Developed Was Used to Predict the Earthquake-Induced Deformations of an Approach Embankment to Bridge …
