ESTIMATION OF EARTHQUAKE-INDUCED SLOPE DEFORMATIONS

Abstract

As a result of displacements induced by earthquakes, mass movements and collapses occur on slopes. Estimating the potential ground displacement resulting from earthquakes is important for both on-slope and below-slope structures. However, the long duration and complexity of dynamic analysis make such studies difficult. Various displacement estimation formulas exist in the literature to address this challenge. In this study, analyses were conducted using Plaxis 2D software, based on the finite element method, on slopes with different geometries and soil properties under different dynamic loadings to calculate the displacements that will occur on slopes due to dynamic effects. The Hardening Soil-Small Strain material model was used to model the soil behavior in the analyses. Dynamic analyses were conducted for slopes with static coefficients of safety between 1.30 and 2.00 using earthquake records of two different magnitudes, and an attempt was made to develop a relationship between the displacements obtained at the top of the slope and parameters such as maximum ground acceleration (PGA), static coefficients of safety, and so on. Consequently, the acceleration-dynamic deformation and static coefficients of safety-dynamic deformation relationships developed in this study can be easily determined at the initial design stage using tables or formulas, without requiring the need for long and laborious dynamic analyses.
