ASTM D4719 - 07 Standard Test Methods for Prebored Pressuremeter Testing in Soils

Size: 1 MB | Format: PDF | Quality: Unspecified | Publisher: ASTM | Year: 2007 | pages: 9

This test method provides a stress-strain response of the soil in situ. A pressuremeter modulus and a limit pressure is obtained for use in geotechnical analysis and foundation design.

The results of this test method are dependent on the degree of disturbance during drilling of the borehole and insertion of the pressuremeter probe. Since disturbance cannot be completely eliminated, the interpretation of the test results should include consideration of conditions during drilling. This disturbance is particularly significant in very soft clays and very loose sands. Disturbance may not be eliminated completely but should be minimized for the prebored pressuremeter design rules to be applicable.
