Conclusions The experience gained showed that, increasing the quality and reliability of other types of field investigations, the ADJ method can be used for solving the following problems of engineering-geological surveys: detailed zoning of rock foundations according to jointing, including a determination of the intense weathering zone and determination of the zone of influence of tectonic deformations; determination of anisotropy of the rock mass with respect to jointing; separation of rock members differing in lithological and petrographic characteristics; evaluation of the change in open jointing during thawing of frozen rocks; selection of characteristics areas for conducting costly point field experimental investigations; extension of the results of experimental investigations at individual points to the mass; evaluation of the intensity and depth of alteration of small jointing under the effect of various factors (blasting, stress relief processes, congelifraction, etc.); determination of the thickness of the unloading zone in tunnels and adits. It is recommended to use the ADJ method at construction sites for checking the quality of the placed concrete, detecting cracks in the concrete structures, evaluating the quality of cementing rocks, selecting the method of conducting blasting operations in order to preserve the foundation rocks, and monitoring the preservation of the rock foundation, particularly when accepting the foundation for concreting works.
