  • The vibration-induced liquefaction in soils is a notable hottopic in geotechnical engineering. The building collapse and embankment burst induced by liquefaction are fatal for the loss of lives and properties of human beings. A series of blasting tests including single explosive charge and multiple underground blasts with millisecond delays are conducted in a large-scale field site filled with saturated sand. The methods of borehole drilling and charge burying, monitoring equipment, design of concrete structure and embankment, and other technical details about blast-induced liquefaction are introduced. The liquefaction mechanism produced by single shallow-buried detonation or multiple blasts is studied firstly. Then the influence factors on the blast-induced liquefaction are analyzed. Based upon these results, the method to produce a large area of liquefaction condition is determined. Finally, the stability of a concrete structure and a soil-embankment on the liquefaction ground is discussed. The successful implementation of blast-induced liquefaction tests can provide references for artificially producing large-scale liquefaction environment.
