Carbon Footprint: Liquefaction Effects On A Private Residence

Abstract

In this study, focus is placed on ground improvement in seismic regions, as a geotechnical application of major economic and environmental consequence. To this end, a pilot framework is developed for assessment of related cost and carbon emissions. For a representative residential structure built on potentially liquefiable ground, three options are considered. The first option is to implement a ground modification countermeasure before constructing the structure. The other options include repair of damage, primarily by re-levelling the structure if the earthquake occurs. For the developer/stakeholder, the initial as well as potential post-earthquake cost and carbon emissions are factors of interest. The a priori ground modification considered for this study is vibro stone columns, and the technique for post-earthquake re-levelling of the residence is compaction grouting. Carbon emissions are computed via process-based life-cycle-assessment (P-LCA). The analysis framework is presented along with the underlying calculation procedures. Potential benefits and shortcomings in terms of cost and carbon emission are contrasted, highlighting significance to the process of decision support.
