Resumen

This research compares the increase in the liquefaction safety factor and the decrease in the settlements produced by liquefaction after applying soil improvement methods that mitigate the soil liquefaction phenomenon. The methods or improvement treatments analyzed are as follows: gravel columns; Rammed Aggregate Pier; and compaction injections. The scenario in which this evaluation was conducted is a sandy soil in the city of Chimbote, Peru, which has all of the necessary characteristics for this phenomenon to occur, namely sandy soil, low relative density, high water table and seismic zone. In addition, there was soil liquefaction in this city in 1970.
