Eurocode 7(1) EN 1997 is intended to be used in conjunction with EN 1990:2002, which establishes the principles and requirements for safety and serviceability, describes the basis of design and verification and gives guidelines for related aspects of structural reliability. (2) EN 1997 is intended to be applied to the geotechnical aspects of the design of buildings and civil engineering works. It is subdivided into various separate parts (see ). (3) EN 1997 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. (4) Numerical values of actions on buildings and civil engineering works to be taken into account in design are provided in EN 1991 for the various types of construction. Actions imposed by the ground, such as earth pressures, shall be calculated according to the rules of EN 1997. (5) Separate European Standards are intended to be used to treat matters of execution and workmanship. They are denoted in the relevant sections. (6) In EN 1997 execution is covered to the extent that is necessary to conform to the assumptions of the design rules. (7) EN 1997 does not cover the special requirements of seismic design. EN 1998 provides additional rules for geotechnical seismic design, which complete or adapt the rules of this standard. EN 1997-2 (1) EN 1997-2 is intended to be used in conjunction with EN 1997-1 and provides rules supplementary to EN 1997-1 related to: planning and reporting of ground investigations; general requirements for a number of commonly used laboratory and field tests; interpretation and evaluation of test results; derivation of values of geotechnical parameters and coefficients. In addition, examples of the application of field test results to design are given. NOTE Establishment of characteristic values is covered in EN 1997-1. (2) This document gives no specific provisions for environmental ground investigations. (3) Only commonly used geotechnical laboratory and field tests are covered in this standard. 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. The laboratory tests on soils are mainly applicable to saturated soils. NOTE It is expected that updates of the present standard will gradually include laboratory and field tests covering additional aspects of soil and rock behaviour. (4) The provisions of this standard apply primarily to projects of geotechnical category 2, as defined in 2.1 of EN 1997-1:2004. The ground investigation requirements for category 1 projects are normally limited as the verifications often will be based on local experience. For geotechnical category 3 projects, the amount of investigations required will normally be at least the same as indicated for geotechnical category 2 projects in the following sections. Additional investigations and more advanced tests, related to the circumstances that place a project in geotechnical category 3, may be necessary. (5) The derivation of parameter values is dedicated primarily to the design of pile and spread foundations based on field testing, as detailed in Annexes D, E, F and G of EN 1997-1:2004.

Requirements for the execution, interpretation and use of results of laboratory tests to assist in the geotechnical design of structures
This standard defines the common application conditions to be used as a basis for the determination of the allowable pressures PFA, PMA and PEA, as defined in EN 805, in the product standards for components to be used in buried pressure pipelines. This standard specifies the application conditions which comprise typical installation conditions including internal and external loads.#,,#
This part of BS 434 provides recommendations and guidance on thegeneral usage of cationic bituminous emulsions on roads and otherpaved areas. The emulsions covered conform to BS 434-1, orBS EN 13808 (modified and non-modified), or are proprietary emulsions.This British Standard provides guidance on where the various processes using bituminous emulsions are suitable for use and indicates where suitable design procedures may be found. Advice is also given on those situations in which the processes are unsuitable or marginally suitable.Where there is an option, performance or outcome specifications havebeen used rather than input or recipe specifications. This follows the general approach adopted for European Standards and the generalmove towards performance specifications by many specifiers.Anionic emulsions are covered only for exceptional circumstances.Cationic emulsions have been specified for most purposes, although insome cases an anionic alternative may be used.
This part of this British Standard contains the method by which the density ofsemi-dry, partially compacted concrete can be obtained for the purpose ofdetermining the quantity of materials necessary to generate a volume of 1 cubicmetre, also known as the “yield”. The method applies to plain concrete madewith aggregate having a nominal maximum aggregate size, Dmax of 40 mm orless but not to concrete with a slump of more than 10 mm when tested inaccordance with BS EN 12350-2.NOTE 1 The method for the determination of density of concrete with a slump ofmore than 10 mm is described in BS EN 12350-6.NOTE 2 This method is not applicable to concrete designed to conform to therequirements of the Specification for Highway Works [1] which describes a specificmethod for to be applied to hydraulically bound materials intended for use inhighway pavements.
This standard gives recommendations and guidance for unreinforcedearthworks forming part of general civil engineering construction,with the exception of dams. This standard also gives recommendationsand guidance for temporary excavations such as trenches and pits.NOTE Reinforced earthworks are covered in BS 8006-1 and BS 8006-2.This document applies to earthworks classified as GeotechnicalCategory 1, 2 and 3 structures as defined in BS EN 1997-1-2004.
