Laboratory verification of blast-induced liquefaction mechanism. Final report Jan-Jul 81
A mechanism for blast-induced liquefaction was tested in a series of high pressure undrained, isotropic compression tests on saturated samples of Eniwetok beach sand and Ottawa sand. Theory, based on inelastic volume compressibility of sand, was shown to be valid for the case of quasi-static, isotropic loading. Specimens of Eniwetok sand subjected to an initial effective stress of 1 MPa were liquefied by a single cycle of loading of 34 MPa. Specimens of Ottawa sand, tested in the same manner, generated excess pore pressure but not enough to completely liquefy the soil. The errors introduced by flexibility of the testing systems were analyzed and found to be insignificant. Suggestions for future research were made.
