PROBLEMS OF CORRELATION BETWEEN DYNAMIC PROBING TEST (DPSH) AND CONE PENETRATION TEST (CPT) FOR COHESIVE SOILS OF LITHUANIA

The paper analyses problems of correlation between the results of dynamic probing (DPSH - Super heavy dynamic probing) and cone penetration test. According to investigations of geological cross-sections of cohesive soils of the territory of Lithuania correlation dependencies are evaluated. Reliability of dynamic probing and modern methods of results correction are discussed. Effect of DPSH rods and lateral stress of soils to the results of probing is evaluated. Correlation dependencies between blow count N and depth of probing and cone resistance q(c) for various cohesive soils found in the territory of Lithuania.
