The effects of some factors

such as impact loading magnitudes

confining pressure and the types of soils on reconsolidation deformation are studied under impact loading. Particularly

the reconsolidation deformation characteristics of a kind of sand-clay mixture sample are discussed according to laboratory test results; and are compared with the saturated soft clay samples. Besides

the disturbance consolidation

the limit pore water pressure

the effect of test conditions on test results

etc. are also discussed. Based on the test results

the problems of secondary consolidation deformation under various drainage conditions are analyzed. These studies have a great significance to dynamic consolidation method for the reinforcement of saturated soft clay foundation.
