Abstract Preview
ISO 22476-7:2012 specifies the equipment requirements, execution of and reporting on borehole jack tests.
It 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.
ISO 22476-7:2012 applies to test depths of < 100 m and to testing either on land or off-shore.
