Sažetak

Application of dynamic penetration is not widely spread, considering the limited number of data that can be obtained. When а larger number of boreholes on terrains built of soft rocks is required, there exists economic justification for the use of certain dynamic tests that can give data about resistance and soil density. Also, in parts where the access is difficult or impossible for the machines for soil probing, penetrometer tests are only possible for obtaining certain parameters. Correlation between point of resistance and shear strength can obtain data of undrained firmness shear strengths for clayey soils, and based on the value of point of resistance the percentage of compaction of soil with quite real accuracy. The dynamic penetration test was applied along the route of the Zenica-Sarajevo railway. Since this is a rarely used type of research, the authors hope that this paper will serve to others as well, towards further research on better correlations between the two types of methods. It is necessary to make the method with penetration as applicable as possible, because it can be used in very inaccessible places with many more test points and does not require large financial investments.
