EN 1997-2 is intended to be used in conjunction with EN 1997-1 and provides rules supplementary to EN 1997-1 related to planning and reporting of ground investigations, general requirements for a range of commonly used laboratory and field tests, interpretation and evaluation of test results and derivation of values of geotechnical parameters and coefficients.
A borehole shall be advanced incrementally to permit intermittent or continuous sampling. Intervals are typically 1.5 m (5 ft) or less in homogeneous strata. Tests and sampling should be done at every change in strata. After the borehole has been advanced to a desired depth and excess cuttings have been removed, testing and sampling can be ...
Today, there are more than 7,000 offshore platforms operating at a water depth up to and exceeding 2000 m. [2] A typical field development extends over tens of square kilometers, and may comprise several fixed structures, infield flowlines with an export pipeline either to the shoreline or connected to a regional trunkline.
A borehole is a narrow shaft bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water ( drilled water well and tube well ), other liquids (such as petroleum ), or gases (such as natural gas ).
A USBR soil scientist advances a Giddings Probe direct push soil sampler.. Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is ...
Johnnie Walker, a former BBC Radio 2 DJ known for hosting the “Sounds of the 70s” show, died Monday. He was 79. The news was announced live on the station by Bob Harris, who took over Johnnie ...
Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...
