- Abstract
The paper summarizes results of numerical analysis of source frequency influence on the quality of seismic recognition of the landslide failure surface. Numerical simulation was carried out for the seismic refraction method in two-dimensional model of landslide. The analyzed model was constructed on the basis of geological engineering model of typical landslide conditions in the Carpathian flysch located in the Mucharz village area. Numerical analysis allowed us to obtain the optimal frequency for recognition of surface failure location. It was shown that frequency above 50 Hz is the most promising in measurements conditions. It was proved that seismic measurements allowed us to get more adequate results in detecting discontinuity borders in comparison with theoretical resolution. Numerical computations were realized by finite difference method using FLAC 5.0 software and their interpretations using Plotrefa software
