The values stated in inch pound units may not aetm exact equivalents; therefore, they shall be used independently of the SI system.

This is typically accomplished by coupling a plank to the ground near the borehole and then impacting the plank in the vertical and horizontal directions.

Two methods are discussed, which include using either one or two downhole sensors receivers. Subscribe on standards with our subscription service.

In addition, they are representative of the significant digits that should generally be retained. Remember me for one month. Your shopping cart is empty. Accurate in-situ P-wave and S-wave velocity profiles are essential in geotechnical foundation designs. Work Item s – proposed revisions of this standard. A preferred method intended to obtain data for use on critical projects where the highest quality data is required is included.

Special consideration should be given to the types of receivers used and their configuration. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. These test methods primarily concern the actual test procedure, data interpretation, and specifications for equipment which will yield uniform test results. Inch-pound units are provided for convenience.

Heavily-damped sensors should not be used so that spectral smearing, phase shifting, and latency response between sensors is avoided.

Standard Test Methods for Downhole Seismic Testing

Data reduction and interpretation astk limited to the identification of various seismic wave types, apparent velocity relation to true velocity, example computations, use of Snell’s law of refraction, and assumptions. The most complete version of this downhole system, as manufactured by Olson Instruments, is comprised of a borehole source capable of generating shear and compressional waves and a pair of matching three component triaxial geophone receivers.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The quality x7400 the results produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities.

Other items addressed include source-to-receiver spacing, drilling, casing, grouting, a procedure for borehole installation, and conducting actual borehole and seismic cone tests. The instruments are coupled to the side of the grouted borehole inclinometer casing, allowing for the detection of shear and compressional waves as they pass between the receivers. Several types of commercially available receivers and recording systems can also be used to conduct an acceptable downhole survey.

It is the responsibility of the sstm of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
