Hybrid Numerical Investigation on Soil-Hammer Interaction

To investigate the mechanism of hammer-soil interaction under the action of dynamic compaction (DC) on a coarse-grained soil foundation,based on the theory of projectile penetration,the continuous-discrete coupling method is used to simulate the hammer-soil interaction process with different hammer shapes and different particle radii.The physical phenomena and mechanical parameters Foundations of aboveground steel tanksc) flat bottom without slope It can be applied in the small tanks where the removing of the water dropped inside into the tank is not required.d) flat bottom with single slope.Can be applied where the diameter D 30 m.This type of bottom requires sloped foundation and the construction of the shell must assure its vertical position.2.Foundations of aboveground steel tanksc) flat bottom without slope It can be applied in the small tanks where the removing of the water dropped inside into the tank is not required.d) flat bottom with single slope.Can be applied where the diameter D 30 m.This type of bottom requires sloped foundation and the construction of the shell must assure its vertical position.2.
