Moving particle simulation-aided soil plasticity analysis for earth pressure balance shield tunnelling

Understanding the relationship between plasticity of muddy soil and earth pressure can be crucial to maintaining tunnel stability and predicting ground behavior during earth pressure balance (EPB) shield tunnelling, a common underground excavation method. Researchers developed small-scale model experimentation combined with moving particle simulation-based computer-aided engineering analysis that reliably predicted soil’s plasticity and its correlating factors without having to deal with the cost and time of on-ground field analysis.
