State of the Art and Practice in Earthquake Induced Soil Liquefaction Assessment


Project Scope:

An ad hoc committee of the National Research Council will solicit input from the technical community and critically examine the technical issues regarding liquefaction hazard evaluation and consequence assessment. The study will assess and evaluate

 

  • Sufficiency, quality, and uncertainties associated with laboratory and in situ field tests, case histories, and physical model tests to develop and assess methods for determining liquefaction triggering, and the resulting loss of soil strength and its consequences;                                                                                                    
  • Methods to conduct and analyze laboratory and physical model testing and to collect and analyze field case history data to determine the triggering of liquefaction, and post-liquefaction soil behavior (e.g. strength loss, dilation, and hardening);
  • Adequacy and accuracy of empirical and mechanistic methods to evaluate liquefaction triggering and post-liquefaction deformations of earth structures and structures founded on or in the earth, such as large embankment dams, levees, dikes, pipelines, highway embankments, bridges, pile-supported decks, and other structural foundations. Effects at large depths and high static shear stresses on liquefaction triggering and post-earthquake shear strength will be among those addressed.

 

The study will focus on developments since the 1996 National Center for Earthquake Engineering Research (NCEER) and the1998 National Science Foundation/NCEER workshops on liquefaction issues and consider data including those related to soil properties, site characterization, ground motions, and observations and measurements of soil response (e.g., post liquefaction deformations). Inherent characteristics associated with the data (e.g., uneven distribution, scarcity, uncertainty) will be investigated. The study will include a workshop on data gathering, vetting of field and laboratory data, and new developments in the assessment of earthquake induced soil liquefaction. The final report will assess the state-of-the-art and practice for liquefaction analyses and will address future directions for research and practice related to (i) collecting, reporting, and assessing the sufficiency and quality of field case history observations as well as in situ field, laboratory, and model test data; (ii) addressing the spatial variability and uncertainty of these data; and (iii) and developing more accurate tools for assessing liquefaction triggering and its consequences.

Dr. Brian F. Atwater
U.S. Geological Survey

BRIAN ATWATER (NAS) is a U.S. Geological Survey geologist affiliated with the University of Washington. His earthquake-related research began in 1983 with using alluvial-fan deposits to estimate recurrence intervals for coseismic growth of an anticline near Coalinga, California. Since 1985 he has focused on earthquake and tsunami hazards at subduction zones. At the Cascadia Subduction Zone he studied geologic evidence of land-level change, tsunamis, and liquefaction. These studies branched into geologic calibrations in Alaska and Chile; comparisons with written records of an Edo-period tsunami in Japan; paleotsunami research in Indonesia and Thailand; and collaborations with scientists from Pakistan. The international umbrellas included fellowships in Japan, USAID projects on Indian Ocean shores, UNESCO projects on the Makran Subduction Zone, and a Fulbright Fellowship in Indonesia. In a Japanese demonstration project that focused on paleoliquefaction, Dr. Atwater used giant sediment slices to learn that subsurface dikes and sills are common beneath Columbia River banks where liquefaction failed to produce surficial evidence during the 1700 Cascadia earthquake. His current work extends to earthquake-hazard assessment in the Caribbean and service on a California advisory board on water resources and ecosystem restoration.

Dr. Ellen Rathje
The University of Texas at Austin

ELLEN RATHJE is the Warren S. Bellows Centennial Professor of Civil Engineering at the University of Texas at Austin. Her research encompasses the seismic stability of earth slopes, site response modeling, liquefaction evaluation and soil improvement, and the application of remote sensing to geotechnical phenomena. Dr. Rathje was one of the developers of a new in situ dynamic liquefaction test, which utilizes a large, truck-mounted hydraulic shaker to induce liquefaction in localized zones of saturated soil. This testing technique is the first of its kind and is expanding the tools available to study liquefaction in situ. Dr. Rathje has also been involved in centrifuge testing to evaluate soil improvement techniques such as prefabricated vertical drains. This research involved centrifuge testing of untreated and drain-treated slopes as well as numerical modeling of the centrifuge tests. Her current research efforts involve the use of remote sensing to measure deformations associated with liquefaction and lateral spreading. Dr. Rathje has also been involved in earthquake reconnaissance efforts through her participation as co-chair of the Geotechnical Extreme Events Reconnaissance (GEER) Association. She has participated and/or led several reconnaissance missions (1999 Kocaeli earthquake in Turkey, 2001 Bhuj earthquake in India, 2004 Niigata-ken Chuetsu earthquake in Japan, and the 2010 Haiti earthquake) and through this work has documented the occurrence of liquefaction during earthquakes. Dr. Rathje was a member of the Board of Directors of the Earthquake Engineering Research Institute (EERI) from 2010-2013 and a member of the Scientific Earthquake Studies Advisory Committee of the U.S. Geological Survey from 2007-2013. She received the Huber Research Prize from the American Society of Civil Engineers (ASCE) in 2010, the Hogentogler Award for outstanding paper from ASTM Committee D18 in 2010 (for a paper on in situ liquefaction testing), the Shamsher Prakash Research Award in 2007, and the Shah Innovation Prize from EERI in 2006.
Dr. James R. Rice
Harvard University

JAMES R. RICE (NAS and NAE) is the Mallinckrodt Professor of Engineering Sciences and Geophysics at Harvard University, in its School of Engineering and Applied Sciences and Department of Earth and Planetary Sciences. From 1965 to 1981, Rice was a professor at the Division of Engineering, Brown University. He holds B.S., M.S., and Ph.D. degrees in mechanics from Lehigh University. Rice studies phenomena relating to stressing, deformation, flow and fracture. That has been directed in recent years to geophysics (seismology, glaciology, tectonophysics), and to civil and environmental engineering hydrology and geomechanics. His seismic studies focus on the nucleation of earthquake rupture, thermo- and hydro-mechanical weakening of fault zones during seismic slip, fracture propagation through branched and offset fault systems, tsunami generation and propagation, and relations among stressing, seismicity, and deformation in or near continental and subduction fault systems, including the physics of aseismic deformation transients. His research related to hydrologic processes, including poroelastic-plastic effects and other fluid interactions in the deformation and failure of earth materials, has application to glacial flows, including rapid and episodic ice motions, glacial earthquakes, and massive ice-sheet under-flooding events as natural hydraulic fractures, and also to submarine and subaerial landslide processes.
