Proposed Standard Test Methods for Cross-Hole Seismic Testing
This paper proposes standard test methods for cross-hole seismic testing. A preferred test method intended for use on critical projects where the highest quality data must be obtained is described, and an optional method intended for use on projects that do not require measurements with the same degree of precision is also presented. Data acquisition equipment, such as seismic sources, receivers, and recording systems, are discussed and various applications of the data addressed, along with acceptable interpretation procedures. Other pertinent items that are addressed include borehole spacing, drilling, casing, grouting, deviation surveys, and actual test conduct. It is noted that a variety of equipment can be used to conduct a satisfactory cross-hole seismic test. As a result, this paper is directed toward the actual test procedure, data interpretation, and specifications for equipment that will yield uniform test results.
