ASTM D – 14 Standard Test Methods for Downhole Seismic Testing
Link to Active This link will always route to the current Active version of the standard. These parameters are used in both analyses of soil behavior under both static and dynamic loads where the elastic constants are input variables into the models defining the different states of deformations such as elastic, elasto-plastic, and failure.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory asym prior to use. Heavily-damped sensors should not be used so that spectral smearing, phase shifting, and latency response between sensors is avoided. In this system, the atm lbf represents a unit of force weightwhile the unit for mass is slugs.
These test methods primarily concern the actu. Data reduction and interpretation is 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.
These dynamic soil and rock properties are often utilized for earthquake design analyses necessary for certain structures, liquefaction potential studies, site development, and dynamic machine foundation design.
Combining values from the two systems may xstm in nonconformance with this standard. Inch-pound units are provided for convenience. Register for a trial account.

Click here for Agents. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. If you like to setup a quick demo, let us know at support madcad.
The OE Website is loaded with Tech Brief and project photos using the equipment shown on this website. Contact Olson Instruments when adding on to an existing system, or purchasing multiple systems as some of the components are common to other test methods. Contact us svenska Login.

Sustainable Development Goals and standardisation, how do they connect? In addition, they are representative of the significant digits that should generally be retained. These test methods primarily concern the actual test procedure, data interpretation, and specifications for equipment which will yield uniform test results.
Several types of commercially available receivers and recording systems can also be used to conduct an acceptable downhole survey. Soil and Rock II: You currently cannot view this content. Please login to your authorized staff account to use this feature. The Downhold Seismic DS investigations are similar to CS investigations, but require only one borehole to provide shear and compressional velocity wave profiles.
The DS method uses a hammer source at the surface to impact a wood plank and generate shear and compressional waves.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.
In addition, the material damping can be determined from CS tests. The electronic file may not be reproduced in any way.

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. A preferred method intended to obtain data for use on critical projects where the highest quality data is required is included.
Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.
