ABSTRACT

A number of different Static & Dynamic penetration tests are used today in site investigation. In Netherlands, SCPT is very common for site investigation whereas in Germany Dynamic Probing is popular.

The aim of study was to correlate SCPT and Dynamic Probing test results. Also if time allows, the statistical correlations should be verified with energy relationship of both tests.

In this research, SCPT and Dynamic Probing test results are correlated. Beside correlation, measure of soil variability is established. On the basis of coefficient of variability, a tentative soil classification is obtained. The research is also directed to find the variability of soil with depth.

The energy of SCPT and Dynamic Probing tests is compared on the basis of test results. Also the energy calculated on the basis of the test results is compared with the theoretically required energy to move the cone to certain specified depth using pile formula. 

The number of reported correlations between SCPT and Dynamic Probing test is very few as compared to the correlations between SCPT and SPT(Standard penetration test). The reason might be the popularity of one type of equipment in one specific country compared to other parts of the world.

The correlations made in this research for South Limburg soils are expected to be useful in Germany and Belgium since South Limburg is the part of the Netherlands that  is located between Germany and Belgium. The same type of soil extends to a large part of Germany. Specially in those cases where only Dynamic Probing test results are available, the  reliable correlations made between the two tests for South Limburg soils will be very useful for the engineers of different countries like Belgium, Germany and Netherlands to get the SCPT values.
