Eurocode 7 - Geotechnical design - Part 1: General rules

Edition date: 2026-10-01
In Force
Available languages: German, English
Summary: 1.1 Scope of EN 1997 1 (1) This document provides general rules for the design and verification of geotechnical structures. (2) This document is applicable for the design and verification of geotechnical structures outside the scope of EN 1997 3. NOTE In this case, additional or amended provisions can be necessary. 1.2 Assumptions (1) In addition to the assumptions given in EN 1990, the provisions of EN 1997 (all parts) assume that: — ground investigations are planned by individuals or organisations with knowledge of potential ground and groundwater conditions; — ground investigations are executed by individuals with appropriate skills and experience; — the evaluation of test results and derivation of ground properties from the ground investigation are carried out by individuals with appropriate geotechnical experience and qualifications; — the data required for design are collected, recorded, and interpreted by appropriately qualified and experienced individuals; — geotechnical structures are designed and verified by individuals with appropriate qualifications and experience in geotechnical design; — adequate continuity and communication exist between the individuals involved in data collection, design, verification and execution. (2) This document is intended to be used in conjunction with EN 1990, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works. NOTE Additional or amended provisions can be necessary for assessment of existing structures, see EN 1990 2. (3) This document is intended to be used in conjunction with EN 1997 2, which gives provisions for determining ground properties from ground investigations. (4) This document is intended to be used in conjunction with EN 1997 3, which gives specific rules for the design and verification of certain types of geotechnical structures. (5) This document is intended to be used in conjunction with other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures.

1 Domaine d'application 1.1 Domaine d'application de l'EN 1997 1 (1) Le présent document donne les règles générales relatives au calcul et à la vérification des structures géotechniques. (2) Le présent document s'applique au calcul et à la vérification des structures géotechniques ne relevant pas du domaine d'application de l'EN 1997 3. NOTE Dans ce cas, des dispositions supplémentaires ou modifiées peuvent être nécessaires. 1.2 Hypothèses (1) Outre les hypothèses données dans l'EN 1990, les dispositions de l'EN 1997 (toutes les parties) admettent par hypothèse que : — des reconnaissances géotechniques soient planifiées par des personnes ou des organismes ayant une connaissance des conditions du terrain et des conditions hydrologiques potentielles ; — des reconnaissances géotechniques soient réalisées par des personnes disposant des compétences et de l'expérience appropriées ; — une évaluation des résultats d'essais et une déduction des propriétés du terrain à partir des reconnaissances géotechniques soient réalisées par des personnes justifiant des qualifications et de l'expérience appropriées en matière de reconnaissance géotechnique ; — les données nécessaires au calcul soient recueillies, enregistrées et interprétées par des personnes suffisamment qualifiées et expérimentées ; — les structures géotechniques soient calculées et vérifiées par des personnes justifiant des qualifications et de l'expérience appropriées en matière de calcul géotechnique ; — il existe une continuité et une communication adéquates entre les personnes concernées par la collecte des données, le dimensionnement, la vérification et l'exécution. (2) Le présent document est destiné à être utilisé conjointement avec l'EN 1990, qui établit les principes et les exigences de sécurité, d'aptitude au service, de robustesse et de durabilité des structures, y compris des structures géotechniques, et d'autres ouvrages d'art. NOTE Des dispositions supplémentaires ou amendées peuvent être nécessaires pour l'évaluation de structures existantes ; voir l'EN 1990 2. (3) Le présent document est destiné à être utilisé conjointement avec l'EN 1997 2, qui donne des dispositions pour la détermination des propriétés des terrains à partir des reconnaissances géotechniques. (4) Le présent document est destiné à être utilisé conjointement avec l'EN 1997 3, qui donne des règles spécifiques pour le calcul et la vérification de certains types de structures géotechniques. (5) Le présent document est destiné à être utilisé conjointement avec les autres Eurocodes pour le calcul des structures géotechniques, y compris des structures géotechniques provisoires.

1.1 Anwendungsbereich von EN 1997 1 (1) Dieses Dokument enthält allgemeine Regeln für Planung und Nachweis von geotechnischen Bauwerken. (2) Dieses Dokument ist anwendbar für die Planung und die Nachweise von geotechnischen Bauwerken, die nicht in den Anwendungsbereich von EN 1997 3 fallen. ANMERKUNG In diesem Fall können zusätzliche oder geänderte Regeln erforderlich sein. 1.2 Voraussetzungen (1) Zusätzlich zu den in EN 1990 genannten Voraussetzungen beruhen die Vorgaben nach EN 1997 (alle Teile) auf folgenden Voraussetzungen: — Baugrunduntersuchungen werden durch Personen oder Organisationen mit Kenntnis der möglichen Baugrundverhältnisse und Grundwasserbedingungen geplant; — Baugrunduntersuchungen werden durch Personen mit entsprechenden Fertigkeiten und Erfahrungen ausgeführt; — die Beurteilung der Versuchsergebnisse und Ableitung der Baugrundkenngrößen aus der Baugrund-untersuchung werden durch Personen mit angemessener Erfahrung und Qualifikation in der Geotechnik ausgeführt; — die für die Bemessung erforderlichen Daten werden durch Personen mit angemessener Qualifikation und Erfahrung gesammelt, dokumentiert und interpretiert; — Planung und Nachweis von geotechnischen Bauwerken werden durch Personen mit angemessenen Qualifikationen und einschlägiger Erfahrung ausgeführt; — es besteht eine angemessene und fortlaufende Kommunikation zwischen den mit Datensammlung, Planung, Nachweis und Ausführung betrauten Personen. (2) Dieses Dokument ist in Verbindung mit EN 1990 anwendbar, das Grundsätze und Anforderungen für die Sicherheit, Gebrauchstauglichkeit, Robustheit und Dauerhaftigkeit von Tragwerken, einschließlich geotechnischen und anderen Bauwerken, festlegt. ANMERKUNG Für die Bewertung vorhandener Bauwerke können zusätzliche oder abgeänderte Regeln erforderlich sein, siehe EN 1990 2. (3) Dieses Dokument ist in Verbindung mit EN 1997 2 anwendbar, das Regeln für die Bestimmung von Baugrundeigenschaften anhand von Baugrunduntersuchungen enthält. (4) Dieses Dokument ist in Verbindung mit EN 1997 3 anwendbar, das spezifische Regeln für die Planung sowie Nachweis bestimmter Arten geotechnischer Bauwerke enthält. (5) Dieses Dokument ist in Verbindung mit anderen Eurocodes für die Planung von geotechnischen Bauwerken, einschließlich geotechnischen Hilfsbauwerken, anwendbar.
