Resilience Model For Coastal-Building Foundations With Time-Variant Soil Strength Due To Water Intrusion In A Changing Climate, Cao Wang, B. M. Ayyub, W. G. P. Kumari

Rock and Soil Mechanics

Groundwater inundation as a consequence of sea level rise triggers significant risks for building foundations in coastal areas. This paper presents a framework to model the resilience of coastal-building foundations in the presence of soil strength deterioration due to water intrusion. The resilience model is mathematically based on the integration of the time-variant performance function within a reference period of interest. A strip foundation is considered, whose ultimate bearing capacity is modeled by the Terzaghi trinomial formula. The rise of groundwater table reduces the strength of soils, and the impact of climate change on groundwater level rise is incorporated in …
