Geotechnical investigation and testing - Field testing - Part 7: Borehole jack test (ISO 22476-7:2012)

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.

Geotechnische Erkundung und Untersuchung - Felduntersuchungen - Teil 7: Seitendruckversuch (ISO 22476-7:2012)

Dieser Teil von ISO 22476 gilt für den Seitendruckversuch in Zusammenhang mit Felduntersuchungen als Teil der geotechnischen Erkundung und Untersuchung nach EN 1997-1 [1] und EN 1997-2 [2].
Dieser Teil von ISO 22476 legt das Verfahren zur Durchführung eines Seitendruckversuchs in einem Bau¬grund fest, der ausreichend steif ist, um durch den Bohrvorgang nicht beeinträchtigt zu werden. Zwei in den Baugrund eingebrachte zylindrische Druckplatten aus Stahl werden aufgespreizt. Der auf die Messsonde aufgebrachte Druck und deren dadurch bewirkte Ausdehnung werden gemessen und aufgezeichnet, um das Verhältnis zwischen Belastung und Aufweitung des Baugrunds im Bereich der erwarteten Bemessungs-belastungen zu ermitteln.
Dieser Teil von ISO 22476 gilt für Versuchstiefen von =< 100 m und für Versuche entweder auf Land oder auf See.

Reconnaissance et essais géotechniques - Essais en place - Partie 7: Essai au dilatomètre rigide diamétral (ISO 22476-7:2012)

L'ISO 22476-7:2012 traite des exigences relatives à l'appareillage, à l'exécution et au compte rendu des essais au dilatomètre rigide diamétral.
L'ISO 22476-7:2012 spécifie le mode opératoire permettant de réaliser un essai au dilatomètre rigide diamétral dans un terrain suffisamment ferme pour ne pas être affecté par l'opération de forage. Deux coquilles de chargement en acier cylindriques et diamétrales sont mises en place dans le terrain et déplacées par pression. La pression appliquée et le déplacement associé sont mesurés et enregistrés de manière à déterminer la relation contrainte-déplacement du terrain dans la plage des contraintes estimées dans le cadre de l'étude.
L'ISO 22476-7:2012 s'applique à des profondeurs d'essai inférieures ou égales à 100 m et aux essais en milieu terrestre ou aquatique.

Geotehnično preiskovanje in preskušanje - Preskušanje na terenu - 7. del: Preskus z bočnim tlakom v vrtini (ISO 22476-7:2012)

Ta del standarda ISO 22476 določa zahteve glede opreme, izvajanja preskusov z bočnim tlakom v vrtini ter poročanja v zvezi z njimi. OPOMBA Ta del standarda ISO 22476 izpolnjuje zahteve za preskuse z bočnim tlakom v vrtini v okviru geotehničnega preiskovanja in preskušanja v skladu s standardoma EN 1997-1 [1] in EN 1997-2 [2]. Ta del standarda ISO 22476 določa postopek za izvajanje preskusa z bočnim tlakom v vrtini v tleh, ki so dovolj trdna, da vrtanje nima negativnega vpliva. V tla se vstavita dve diametrični cilindrični jekleni nosilni plošči in razpreta z uporabo pritiska. Uporabljeni pritisk in povezano odprtje sonde se izmerita in zabeležita, da se pridobi odvisnost med napetostmi in deformacijami tal za razpon pričakovane projektne obremenitve. Ta del standarda ISO 22476 se uporablja za preskusne globine ≤ 100 m in preskušanje na kopnem ali na morju.
