Abstract

Research purposes: The purpose of bringing the multi-yield surface model into the soil mass dynamic finite element calculations is to verify its rationality and validity through the construction practice.

Research conclusions: The multi-yield surface model has its popularity and flexibility to describe the characteristic of the soil mass and the previous calculation with the multi-yield surface model fovoured safety.

Key words

saturated sands / multi-yield surface dynamic model / seismic response study / finite element
