GeoStudio Example of Heave Due to Infiltration

This document is a technical report that presents an example of heave due to infiltration using the GeoStudio software. It outlines the impact of swelling soils on foundations and roads, particularly in response to climatic changes. The case study references the work of Vu and Fredlund (2006), which discusses swelling soil caused by infiltration from precipitation and irrigation. The report details the numerical simulation setup, including the configuration of a 5 m deep layer of highly plastic clay and the application of an infiltration flux rate. It describes the analysis process, which includes establishing initial water pressures and stresses, followed by a consolidation simulation to model swelling. The document also presents various figures illustrating the analysis configuration, water pressure profiles, and heave results over time. The findings indicate that SIGMA/W can effectively estimate heave in unsaturated soils, providing insights into the mechanisms of infiltration and its effects on structures.
