"text": "
The 1978 Rigaud landslide in Québec was triggered during pile driving and caused a rapid retrogressive failure in clay. Our team collaborated with the Memorial University of Newfoundland to co-author a study, published in the Canadian Geotechnical Journal, that uses advanced large-strain finite element modeling to understand how the failure started and spread.
The modeling shows that pile installation can create localized shear bands that propagate into a larger landslide without additional loading. The work highlights why advanced numerical tools are important for assessing construction risks in sensitive clay environments.
