ABSTRACT
In Russia, Cone Penetration Testing (CPT) is developing towards the use of heavy cone penetration rigs to evaluate soil conditions and in particular, calculate the bearing capacity of driven piles. This trend was formed in the former USSR as early as fifty years ago, when mass construction was reoriented toward wide application of precast reinforced concrete and driven piles. The parameters of pile foundations were developed based on the CPT data. In subsequent decades, the range of tasks to be solved by means of CPT significantly expanded, calculations were more reliable and CPT procedures improved.
