Abstract
Purpose
This study aims to propose another alternative numerical modelling tool, i.e. ABAQUS, to simulate a fully coupled seepage-deformation analysis in unsaturated slope subjected to rainfall infiltration.
Design/methodology/approach
The effect of rainfall infiltration on the response of pore water pressure and factor of safety has been analysed and discussed. The results of this study have also been validated based on the results of field monitoring and previous numerical modelling.
Findings
The results from ABAQUS show a better agreement with those from field monitoring compared to other numerical modelling tools.
Originality/value
The procedures adopted in this study can be adopted and used as a guide to model similar slope problems in ABAQUS.
