Abstract
It is proposed to apply a set of geophysical methods to engineering surveys when designing and operating linear underground constructions within pipelines. A new method of resonance acoustic profiling being integrated in conventional electrical methods, will enhance the validity of the research data. The study allows for identifying the areas best fitting for laying and operating the pipeline transport system. The paper provides a complex of geophysical methods to guarantee safety standards on the pipeline transport systems when affected by natural and anthropogenic hazards. The study of resonance acoustic profiling will provide data on geological sections, landslide areas mapping, rockfalls, water intrusion, water-bearing horizons, zones of tectonic disturbances and karst cavities. The electrical methods allow for determining probable areas of corrosion sites on the pipeline transport systems: VES (vertical electrical sounding), “remote electrode” (electrometric survey), measuring potential gradient and SEP (symmetrical electrical profiling), in particular.
