| 摘要： | The New Madrid Seismic Zone (NMSZ) is the location of several of the largest earthquake events (1811-1812) in the contiguous United States. Due to the infrequent nature of earthquake occurrence in this region, little attention has been paid in the past three decades to its potential threat to regional and national transportation infrastructure. This potential threat is real as inferred from the January 26, 2001, Kutch Earthquake in India, which occurred in a seismic and geological environment similar to the NMSZ and resulted in an estimated 0.45 million deaths and injuries as well as $5 billion in economic losses. This study represents the first systematic investigation in the vicinity of the NMSZ, involving seismologists, geologists, geotechnical and structural engineers, and economists. The objective of this study is to improve earthquake resistance and mitigate earthquake damage to highway transportation networks, including loss of bridges and highways. This is accomplished by developing new seismic design and assessment methodologies, by improving seismic retrofitting measures, and by exchanging and transferring new technologies. The main topics of this study included near-field rock and ground motion, deep soil deposit response, bridge response to near-field ground motion, seismic retrofit of bridge systems, loss estimation methodology, and post-earthquake assessment of structural conditions. |
