EFFECTS OF SAND COMPACTION PILE DRIVING ON GEOTECHNICAL PROPERTIES OF CLAY LAYER
In this paper, effects of the disturbance by the sand compaction pile (SCP) driving on geotechnical properties of clay inside and outside the improved area were investigated based on about 1400 laboratory tests, and following results were obtained: in the area improved by the SCP, the natural water content decreases with time, and even outside of the improved area, the water content decreases; the compression indices of clay obtained before the SCP driving are on the line proposed by Ogawa and due to the SCP driving operation, the compression index decreases; and, unconfined shear strength inside the improved area increases rapidly, however, outside the improved area the SCP driving reduces the shear strength by about 10% and the shear strength does not recover within one year.
