An analytical investigation and laboratory study on gravity effects in small-scale modeling have been performed. The appropriate scaling length for ground movement is identified as lGrho g, when gravity effects are important. Dimensionless gravity parameter, rho lambdaG, and impact energy parameter, WHG lambda.cubed, are identified as the key governing parameters for the problem. Laboratory techniques and procedures have been developed for compensating gravity effect without using artificially induced gravity. Experimental results were summarized in twelve tables and twelve graphs.
