“…Artificial fill in the port areas of Port-au-Prince and Carrefour experienced extensive liquefaction, lateral spreading, and settlement damage. At the Port de Port-au-Prince, liquefaction-induced lateral spreading (Figure 4) resulted in the collapse of the pile-supported North Wharf, damage to two steel-frame warehouses, and other port facilities (Green et al 2011, Werner et al 2011. Geotechnical site investigations performed after the earthquake includes soil borings with standard penetration tests (SPT), dynamic cone penetration tests (DCPT), and surface wave (MASW and SASW) tests (Green et al 2011).…”

“…Green et al (2011) also compare observed values of permanent deformation with estimates obtained from various empirical methods and found that the observed values generally exceed the estimated values. Ground-motion amplification in the soft fill soils was likely a contributing factor to the partial collapse of and extensive damage to the remaining portion of the South Pier at the Port de Port-au-Prince (Werner et al 2011).…”

Overview of the 2010 Haiti Earthquake

The 12 January 2010 Mw 7.0 earthquake in the Republic of Haiti caused an estimated 300,000 deaths, displaced more than a million people, and damaged nearly half of all structures in the epicentral area. We provide an overview of the historical, seismological, geotechnical, structural, lifeline-related, and socioeconomic factors that contributed to the catastrophe. We also describe some of the many challenges that must be overcome to enable Haiti to recover from this event. Detailed analyses of these issues are presented in other papers in this volume.

Geotechnical Aspects of Failures at Port-au-Prince Seaport during the 12 January 2010 Haiti Earthquake

et al. 2011

View full text Add to dashboard Cite

Presented herein are the results of geotechnical investigations and subsequent laboratory and data analyses of the Port-au-Prince seaport following the Mw7.0 2010 Haiti earthquake. The earthquake caused catastrophic ground failures in calcareous-sand artificial fills at the seaport, including liquefaction, lateral spreads, differential settlements, and collapse of the pile-supported wharf and pier. The site characterization entailed geotechnical borings, hand-auger borings, standard penetration tests, and dynamic cone penetration tests. The laboratory tests included grain size and carbonate content tests. The observations and results presented herein add valuable field performance data for calcareous sands, which are relatively lacking in liquefaction case history databases, and the overall response of the artificial fills are consistent with predictions made using semi-empirical relations developed primarily from field data of silica sands.

“…Several ports at Izmit Bay faced substantial damage during the Kocaeli earthquake (Erdik, 2001). Recently, the Haiti earthquake (2010) has caused failure to a pile-supported wharf and partial collapse to a pile-supported pier at Port-au-Prince (Werner et al, 2011).…”

In this study, the seismic vulnerability of a pile-supported wharf is assessed. Due to common lack of empirical data, the analytical fragility curves are developed using the results of the dynamic analysis of wharf subjected to the different time histories. Fragility curves are developed considering three engineering demand parameters, including displacement ductility factor (m d ), differential settlement between deck and behind land and normalised residual horizontal displacement (NRHD). A sensitivity analysis using both the first-order second-moment method and the tornado diagram analysis is then carried out to evaluate the effects of uncertainties associated with geotechnical parameters in the seismic performance of the wharf. Adopted fragility curves are useful to seismic risk assessment. They can also be used to optimise wharf-retrofit methods. The results of sensitivity analysis demonstrate that uncertainties associated with the permeability of hydraulic placed sand fill contribute most to the variance of both NRHD and m d . While in the case of differential settlement, the friction angle of rock fill contributes most to the variance.
