A platform for research: civil engineering, architecture and urbanism
A research project was initiated though State Planning and Research (SP&R) funding to learn how well ground penetrating radar (GPR) can supplement or replace conventional test borings. The objective of the research was to determine if GPR could distinguish between and accurately determine the depth to different soil layers, locate the bedrock surface, find and measure the extent of bedrock fractures and subsurface voids, and map river bottom profiles within different locations throughout New Hampshire. GPR investigations were conducted at locations between test borings or where test borings could not be taken because of time constraints or difficulties with drill rig access. To date, GPR has been used as a supplement to the conventional test borings or as a sole source of subsurface information on a total of seventeen geotechnical projects. This report discusses the use of GPR on eight of these seventeen projects and includes sites where GPR was very effective, moderately helpful and of little use. Techniques employed for using GPR, and how the results were calibrated and verified are included in this report.
