Abstract
Ground failure caused by liquefaction is a major cause of earthquake damage and casualties during many history earthquakes. The gravels liquefaction extensively occurred following the 2008 Wenchuan Ms8.0 Earthquake, and 70-80% liquefied sites generated lots of 100 meter to hundreds kilometer long and 5 centimeter to 50 centimeter wide ground fissures, which intersected house, farmland, etc. and caused serous damage. The mechanism of the building damage and ground fissures were investigated by borehole drilling and Multi-Channels Electricity Resistance Test. The detailed in-situ tests and comparison show that: (1) The building, whose foundation intersected by liquefaction, suffered more severe damages than its surrounding buildings; (2) The abundant ground fissures were generated by gravels liquefaction rather than the raptures or secondary faults; (3)The fundamental conditions for the generation of ground fissures by liquefaction are: flat ground surface (slop less than 3%), horizontal non uniform distribution of liquefiable soils.
