This part of ISO 22476 specifies the equipment requirements, execution of and reporting on borehole jack tests.<\/p>\n

\n

NOTE This part of ISO 22476 fulfils the requirements for borehole jack tests as part of geotechnical investigation and testing according to EN 1997-1[<\/sup>1<\/sup>]<\/sup> and EN 1997-2.[<\/sup>2<\/sup>]<\/sup><\/p>\n<\/blockquote>\n

This part of ISO 22476 specifies the procedure for conducting a borehole jack test in ground stiff enough not to be adversely affected by the drilling operation. Two diametral cylindrical steel loading plates are placed in the ground and opened by pressure. Pressure applied to, and associated opening of the probe are measured and recorded so as to obtain a stress-displacement relationship of the ground for the range of the expected design stress.<\/p>\n

This part of ISO 22476 applies to test depths of  \u2264 100 m and to testing either on land or off-shore.<\/p>\n
