Abstract

1.1.1 Scope of Eurocode 7 (1)P Eurocode 7 applies to the geotechnical aspects of the design of buildings and civil engineering works. It is subdivided into various separate parts, (see 1.1.2). (2)P Eurocode 7 is concerned with the requirements for strength, stability, serviceability and durability of structures. Other requirements, e.g. concerning thermal or sound insulation, are not considered. (3)P Eurocode 7 shall be used in conjunction with ENV 1991-1 "Basis of Design" of Eurocode 1 "Basis of Design and Actions on Structures" which establishes the principles and requirements for safety and serviceability, describes the basis for design and verification and gives guidelines for related aspects of structural reliability. (4)P Eurocode 7 gives the rules to calculate actions originating from the ground such as earth pressures. Numerical values of actions on buildings and civil engineering works to be taken into account in the design are provided in ENV 1991 Eurocode 1 "Basis of Design and Actions on Structures" applicable to the various types of construction. (5)P In Eurocode 7 execution is covered to the extent that is necessary to indicate the quality of the construction materials and products which should be used and the standard of workmanship on site needed to comply with the assumptions of the design rules. Generally, the rules related to execution and workmanship are to be considered as minimum requirements which may have to be further developed for particular types of buildings or civil engineering works and methods of construction. (6)P Eurocode 7 does not cover the special requirements of seismic design. Eurocode 8, "Design provisions for earthquake resistance of structures" provides additional rules for seismic design which complete or adapt the rules of Eurocode 7. 1.1.2 Scope of ENV 1997-2 (1)P This prestandard provides requirements for the execution, interpretation and use of geotechnical laboratory tests. The standard aims at providing assistance for the geotechnical design of structures. It does not replace national test standards on testing procedures. (2) The provisions of this document are planned primarily for projects of Geotechnical Category 2, as defined in 2.1 of ENV 1997-1. (3)P ENV 1997-2 shall be used in conjunction with ENV 1997-1. (4) For each of the laboratory tests included, this prestandard presents the objective and the requirements of the test. The requirements are related to test programme, test apparatus and testing procedures, and the evaluation and presentation of the test results. (4) Only commonly used geotechnical laboratory tests are covered in this prestandard. These were selected on the basis of their importance in geotechnical practice, availability in commercial geotechnical laboratories and existence of an accepted testing procedure in Europe. Tests less commonly used, especially more advanced tests, which may be essential for design of structures within Geotechnical Category 3, as defined in 2.1 of ENV 1997-1, are mentioned in connection with related tests. Unsaturated soils are not covered. The parameters needed for e.g. finite element calculations (Poisson’s ratio, shear modulus and Young’s modulus) are not dealt with either. It is expected that updates of the present prestandard will gradually include more advanced laboratory tests, unsaturated soils and deformation parameters. (5) This document is meant for the person responsible for a geotechnical design.
