v2.03.200 SDLP200 — Comparison of the earthquake resistance of a homogeneous embankment between POST_NEWMARK and GeoSlope

Summary:

This test compares the results of estimating the static and dynamic safety factor for a homogeneous embankment by POST_NEWMARK with the GeoSlope software, whose solution is part of the verification file of this software for the Newmark method [1].

• 1. Reference problem
  • 1.1. The aim is to determine the seismic response of a homogeneous embankment and to calculate the evolution of the safety factor during the earthquake along a pre-determined sliding line.
  • 1.2. To do this, the modeling is divided into three parts:
  • 1.3. Geometry
  • 1.4. Material properties
  • 1.5. Boundary conditions and mechanical loads
  • 1.6. Initial conditions
• 2. Benchmark solution
• 3. Modeling A
  • 3.1. Characteristics of modeling
  • 3.2. Tested sizes and results
• 4. B modeling
  • 4.1. Characteristics of modeling
  • 4.2. Tested sizes and results
• 5. Analysis of the results
• 6. Bibliography
