- Abstract
In order to study the reinforcement process and effect of different energy levels of dynamic compation,three energy levels of dynamic compation experiments with 3000,6000,10000 KN•m are proceed on deep gravel filling foundation.Get datas of ramming settlement , pore water pressure,vibrating velocity during dynamic compaction and datas of rayleigh wave test, super-heavy dynamic pentration test, shallow plate loading test after dynamic compation. Analysis of datas,conclude that the first three cumulative ramming settlement accounts for 50% of the total;For deep gravel filling foundation, can’t consider the dissipation of excess pore water pressure,can continuously construct.;The spread of vibration in the soil,tangential velacity is maximum,followed by the vertical velocity and the radial velocity is minimum,the safety distance of general civil construction is 20 to 40 meters,the safety distance of industrial and commercial buildings is 15 to 30 meters, and advice the selection of safe distance should be subject to the last time ramming; The rayleigh wave’s velocity of surface soil is decreased with high energy dynamic compaction;. The effective reinforcement depths of 3000,6000,10000 KN•m are 6,9and12 meters, correction factor of menard formula is 0.35 to 0.41.
