Geotechnical investigation and testing - Geohydraulic testing - Part 3: Water pressure tests in rock (ISO 22282-3:2012)

ISO 22282-3:2012 specifies the requirements for water pressures tests (WPT) carried out in boreholes drilled into rock as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.
The tests are used to investigate the following:
hydraulic properties of the rock mass, which are mainly governed by discontinuities;
absorption capacity of the rock mass;
tightness of the rock mass;
effectiveness of grouting;
geomechanical behaviour, e.g. hydrofracturing, hydrojacking.

Geotechnische Erkundung und Untersuchung - Geohydraulische Versuche - Teil 3: Wasserdruckversuch in Fels (ISO 22282-3:2012)

Dieser Teil von ISO 22282 behandelt die Anforderungen an Wasserdruckversuche (WPT, en: water pressure
tests) in Bohrlöchern, die als Teil der geotechnischen Erkundung und Untersuchung nach EN 1997-1 und
EN 1997-2 in Fels hergestellt werden.
Die Versuche werden durchgeführt, um Folgendes zu untersuchen:
 hydraulische Eigenschaften des Gebirges, die überwiegend durch Trennflächen bestimmt werden;
 Absorptionsvermögen des Gebirges;
 Dichtheit des Gebirges;
 Wirksamkeit des Verpressens;
 geomechanisches Verhalten, z. B. hydraulisches Aufspalten, hydraulisches Aufweiten.
Viele der sich bei den geohydraulischen Versuchen ergebenden Auswirkungen werden nicht nur durch den
Baugrund selbst beeinflusst, sondern sind Ergebnis der Versuchsverfahren. Historisch gesehen wurde der
Wasserdruckversuch auf der Grundlage der Annahme bewertet, dass ein stationäres Verhalten erreicht wird.
In jüngster Zeit erfolgte Fortschritte in der Geohydraulik haben jedoch gezeigt, dass häufig transiente
Phänomene vorliegen. In diesem Teil von ISO 22282 wird der Ansatz verfolgt, die Grenzen bestimmter
Versuchsverfahren

Geotehnično preiskovanje in preskušanje - Hidrogeološke preiskave - 3. del: Tlačni preskus v kamninah (VDP) (ISO 22282-3:2012)

Ta del standarda ISO 22282 določa zahteve za preizkuse tlaka vode, izvedene v vrtinah, izvrtanih v kamnine, kot del geotehničnega raziskovanja in preizkušanja v skladu s standardoma EN 1997-1 in EN 1997-2. Ti preizkusi se uporabljajo za raziskovanje naslednjega: – hidravlične lastnosti kamninske mase, pri kateri so pogoste prekinitve; – zmožnost absorpcije kamninske mase; tesnjenje kamninske mase; učinkovitost injeciranja; geomehansko delovanje, npr. hidravlično razpokanje, hidravlično lomljenje. Na veliko geohidravličnih preizkusov ne vplivajo sama tla, ampak preizkusni postopek. V preteklosti se je preizkus tlaka vode ocenjeval na podlagi predpostavke, da je doseženo mirujoče stanje. Nedavna odkritja na področju geohidravlike kažejo, da so velikokrat prisotni prehodni pojavi. Osrednji predmet obravnave v tem delu standarda ISO 22282 so omejitve nekaterih preizkusnih postopkov brez prestrogega omejevanja potrebne opreme.
