Improving the quality control of Cofra Roller Compaction: A study on the relation between the impact acceleration and the soil compaction

Ground improvement in the form of soil compaction plays a important part in reclamation projects. The development of the Cofra Roller Compaction (CRC), a non-circular impact roller, has proven to be valuable in these projects. However, the heterogeneity of the subsoil causes locally a non-uniform degree of compaction. Traditional compaction...

Finite Element analysis of soft boundary effects on the behaviour of shallow foundations

The response of a shallow foundation has been investigated by numerical simulations in a series of 1g small scale tests using the Finite Element Method. In this numerical study, special attention has been given to the influence of soft boundaries as a measure to counteract boundary effects, since limitations of space were present in the...
