Abstract

Summary

Crosshole seismic testing (CST) is one of the most effective methods for designing highly sensitive facilities for nuclear construction and can be successfully applied both at the survey stage and after commissioning. On the example of geophysical investigations carried out at the prospective site of the NPP construction, the results of CST on pressure and shear waves are shown. The results of determining the dynamic parameters of soils (Young’s modulus, shear modulus, Poisson’s ratio) and their distribution in the inter-well space are presented. Also, the work shows the result of applying the technique for allocation the fields of incident and reflected waves obtained as a result of seismic cone penetration test (SCPTu) to a depths of 20–30 meters for the detailed layering of the geological section.
