Highway System Damage from Peru's 15Aug2007 M8.0 Earthquake

摘要

The performance of Peru's highway system in this M8.0 earthquake is relevant since the infrastructure was built using AASHTO specifications. The Pisco earthquake of July 2007 was a strong and unusually long-period earthquake. Soil conditions and ground water levels led to widespread liquefaction contributing to more highway damage than ground shaking did. This reconnaissance survey illustrates why geotechnical considerations are paramount. Because some bridges were subject to secondary hazards such as rockfall, there is also a case for consideration of multiple hazards during the design or retrofit of bridges.
