Field test of densification method by means of controlled blasting as remedial measures against soil liquefaction
Japanese Geotechnical Journal
Applicability of densification method by means of controlled blasting is examined by three field tests, and design formulae are proposed. Sand, silt and fill grounds are examined. Blasting is designed to install in the borehole which are arranged with several meters distance from each other, and fired with a little time lags. Water boiled out from the ground and the ground surface subsided after blasting. Since the SPT-N values increases according to the settlement of the ground, it can be useddoi:10.3208/jgs.2.125 fatcat:fyp7jrsd7ffildw2hgzuva7kna
