Banqiao school building had to be demolished for rebuilding because of severe damage induced by liquefaction following the 2008 Wenchuan Ms 8.0 Earthquake. The mechanism of the building damage and the characteristics of liquefied soils were investigated by trench, borehole drilling, and Dynamic Penetration Test. The detailed field investigation and in-situ tests show that: (1) The Banqiao school building suffered more severe damages than its surrounding buildings from the liquefaction rather than inertia force of shaking during the earthquake; (2) The subsurface liquefied soils are gravelly soils at the depth of 3.0 to 6.1m, which are significant different from the ejected fine sands; (3) It is unreasonable to regard gravels as non-liquefiable soils and a new procedure for gravels liquefaction evaluation need to be developed.
