1.1 Scope of EN 1997‑1

(1) This document provides general rules for the design and vérification of geotechnical structures.

(2) This document is applicable for the design and vérification 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 qualifiéd and experienced individuals;

— geotechnical structures are designed and vérifiéd by individuals with appropriate qualifications and experience in geotechnical design;

— adequate continuity and communication exist between the individuals involved in data collection, design, vérification 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 spécific rules for the design and vérification 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.

1.1 Scope of EN 1997-2

(1) This document provides rules for determining ground properties for the design and verification of geotechnical structures.

(2) This document covers requirements and guidance for planning ground investigations, collecting information about ground properties and groundwater conditions, and preparation of the Ground Model.

(3) This document covers requirements and guidance for the selection of field investigation and laboratory test methods to obtain derived values of ground properties.

(4) This document covers requirements and guidance on the presentation of the results of ground investigation, including derived values of ground properties, in the Ground Investigation Report.

1.2 Assumptions

(1) The provisions in EN 1997-2 are based on the assumptions given in EN 1990 and EN 1997-1.

(2) This document is intended to be used in conjunction with EN 1997-1, which provides general rules for design and verification of all geotechnical structures.

(3) This document is intended to be used in conjunction with EN 1997-3, which provides specific rules for design and verification of certain types of geotechnical structures.

(4) This document is intended to be used in conjunction with EN 1998-1-1 which provides the requirements for the ground properties needed to define the seismic action.

(5) This document is intended to be used in conjunction with EN 1998-5 which provides rules for the design of geotechnical structures in seismic regions. 

1.1 Scope of EN 1997-3

(1) This document provides specific rules to be applied in the design and verification of geotechnical structures.
