Regional Meeting Webinar: Seismic Response of Fine Grained SoilPresented by Dr. Jonathan Bray, UC Berkeley Faculty Chair Liquefaction triggering procedures provided results consistent with observations of liquefaction across much of Christchurch, New Zealand during the 2010-2011 Canterbury earthquakes. However, there are cases where liquefaction assessment methods indicate that there should have been severe liquefaction-induced ground failure, yet none was observed. The overestimation of liquefaction-induced ground failure by current procedures is troublesome because engineers often require expensive ground improvement or building foundations where these procedures indicate that liquefaction is likely. The over-estimation of liquefaction triggering by current procedures is due to their inability to capture the seismic performance of stratified silty soil deposits. The empirical database used to develop these procedures consists primarily of liquefaction triggering data from sand sites.
