Soil Pore Gas Pressure Measurements at the Nevada Test Site,
Abstract
This paper describes a system that monitors soil pore pressure in dry reconstituted soil, serving as the tamping and containing medium for experimental explosions. This system has proven to be reliable and stable over the several years that it has been maintained and operated. It yields information on compression of the soil due to the initial shock wave, rarefactions due to settling and variations that correlate well with variations in atmospheric pressure. The burial depth of sensing systems ranges from a few feet to over 1,000 feet in alluvium-like material. The primary sensing device is a pressure transducer in a protective structure sometimes referred to as a cowbell or a rocket. The why, when and where of the measurements is given along with the system calibration, instrument installation, recording and data reduction. Examples of data and their analysis are presented.
