Abstract

Extensive damage took place in the quay walls in the Ports of Valparaíso and San Antonio during the Chilean earthquake of March 1985. Different types of retaining structures such as gravity retaining walls built with concrete blocks, sheetpiles and decks on vertical piles were subjected to large shaking ranging from 0.3 - 0.45g at Valparaíso Port to more than 0.6g at San Antonio. Some of the retaining structures collapsed and others behave quite well. In addition, some liquefaction and settlements in the sandy fill below the yards did occur at San Antonio, along with permanent displacements in the fill slope behind some of the decks supported by piles. The behavior of 7 berths at Valparaíso and 7 berths at San Antonio is discussed taking into account soil characteristics and field measurements performed after the earthquake.

Failures of Quay Walls During Chilean Earthquake of March 1985

St. Louis, Missouri

Extensive damage took place in the quay walls in the Ports of Valparaíso and San Antonio during the Chilean earthquake of March 1985. Different types of retaining structures such as gravity retaining walls built with concrete blocks, sheetpiles and decks on vertical piles were subjected to large shaking ranging from 0.3 - 0.45g at Valparaíso Port to more than 0.6g at San Antonio. Some of the retaining structures collapsed and others behave quite well. In addition, some liquefaction and settlements in the sandy fill below the yards did occur at San Antonio, along with permanent displacements in the fill slope behind some of the decks supported by piles. The behavior of 7 berths at Valparaíso and 7 berths at San Antonio is discussed taking into account soil characteristics and field measurements performed after the earthquake.
