GPR data interpretation in the landslides and subgrade slope surveys

Abstract

The paper describes results of GPR survey of multi-layered slopes of transport structures. A brief review of this problem by domestic and foreign researchers is presented. The significance of this work is determined by complexity of GPR data interpretation when the GPR survey is conducted in a common offset or common midpoint mode in case of dipping layers. The typical patterns are obtained, the groups of the same reflection events are picked and possible reasons of them are stated by numerical modeling using GprMax software. The technique of ground velocities finding in case of GPR survey of dipping layers is proposed.
