Repeated liquefaction of soil during an earthquake is extremely damaging to soil-structure systems. A new paper in ASCE's Journal of Geotechnical and Geoenvironmental Engineering compares two liquefaction case histories with different pore pressure responses, yet similar silty sand layers, cone penetration and groundwater tables. The authors draw conclusions through a detailed analysis of similarities and differences. Read their complete findings free for a limited time, courtesy of ASCE Library.
