    Effects of Ground Failure on Bridges, Roads, and Railroads
    (EARTHQUAKE ENGINEERING RESEARCH INST, 2012) Ledezma, Christian; Hutchinson, Tara; Ashford, Scott A.; Moss, Robb; Arduino, Pedro; Bray, Jonathan D.; Olson, Scott; Hashash, Youssef M. A.; Verdugo, Ramon; Frost, David; Kayen, Robert; Rollins, Kyle
    The long duration and strong velocity content of the motions produced by the 27 February 2010 Maule earthquake resulted in widespread liquefaction and lateral spreading in several urban and other regions of Chile. In particular, critical lifeline structures such as bridges, roadway embankments, and railroads were damaged by ground shaking and ground failure. This paper describes the effects that ground failure had on a number of bridges, roadway embankments, and railroads during this major earthquake. [DOI: 10.1193/1.4000024]

    Effects of Ground Failure on Buildings, Ports, and Industrial Facilities
    (EARTHQUAKE ENGINEERING RESEARCH INST, 2012) Bray, Jonathan; Rollins, Kyle; Hutchinson, Tara; Verdugo, Ramon; Ledezma, Christian; Mylonakis, George; Assimaki, Dominic; Montalva, Gonzalo; Arduino, Pedro; Olson, Scott M.; Kayen, Robert; Hashash, Youssef M. A.; Candia, Gabriel
    Soil liquefaction occurred at many sites during the 2010 Maule, Chile, earth-quake, often leading to ground failure and lateral spreading. Of particular interest are the effects of liquefaction on built infrastructure. Several buildings were damaged significantly due to foundation movements resulting from liquefaction. Liquefaction-induced ground failure also displaced and distorted waterfront structures, which adversely impacted the operation of some of Chile's key port facilities. Important case histories that document the effects of ground failure on buildings, ports, and industrial facilities are presented in this paper. [DOI: 10.1193/1.4000034]
