摘要：

The technique of using explosives to achieve compaction of a soil mass has been tested in connection to a road construction project in the central part of Sweden. The natural soil, 2 to 5 meters of organic soil (peat), was excavated and replaced with a fine grained till. The test site was instrumented with pore pressure gauges, inclinometers and a device for settlement measuring. The fill was subjected to compaction by blasting at three different occasions, each blasting separated by, at least, 2 to 3 weeks. In order to obtain the fill stiffness determination of Raleigh wave travelling velocities were carried out using the SASW (Spectral Analysis of Surface Wa;es) technique. These measurement were carried out at three different occasions with the aim to detect changes in stiffness due to the "compaction by blasting" activities.
