Abstract
A new technology of dynamic compaction method is successfully used to reinforce the saturated soft soil foundation. The field monitoring laws of lateral displacement of the foundation after dynamic compaction, the increasing and dissipation regularity of the excess pore water pressure are analyzed and discussed. The improvement effect is verified by static cone penetration test and loading test. The determination methods of effective reinforcement depth after dynamic compaction are put forward. The practice shows that, by field-testing methods, such as static cone penetration test and pore water piezometer test, to determine the effective reinforcement depth after dynamic compaction and other design parameters is reliable.
