EN 1997-2-2007歐洲法規(guī)7.土工設(shè)計(jì).第2部分:土地勘測(cè)和測(cè)試［代替:CEN ENV 1997-3］

Eurocode 7(1) EN 1997 is intended to be used in conjunon 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 asps of structural reliability. (2) EN 1997 is intended to be applied to the geotechnical asps of the design of buildings and civil eneering 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 insation, are not considered. (4) Numerical values of aons on buildings and civil eneering works to be taken into account in design are provided in EN 1991 for the various types of construon. Aons imposed by the ground, such as earth pressures, shall be calcated according to the res of EN 1997. (5) Separate European s are intended to be used to treat matters of execution and workmanship. They are denoted in the relevant sions. (6) In EN 1997 execution is covered to the extent that is necessary to conform to the assumptions of the design res. (7) EN 1997 does not cover the special requirements of seismic design. EN 1998 provides additional res for geotechnical seismic design, which complete or adapt the res of this . EN 1997-2 (1) EN 1997-2 is intended to be used in conjunon with EN 1997-1 and provides res 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 rests; derivation of values of geotechnical parameters and coefficients. In addition, examples of the application of field test rests 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 . These were seled on the basis of their importance in geotechnical prace, 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 exped that updates of the present will gradually include laboratory and field tests covering additional asps of soil and rock behaviour. (4) The provisions of this apply primarily to projs of geotechnical category 2, as defined in 2.1 of EN 1997-1:2004. The ground investigation requirements for category 1 projs are normally limited as the verifications often will be based on local experience. For geotechnical category 3 projs, the amount of investigations required will normally be at least the same as indicated for geotechnical category 2 projs in the following sions. Additional investigations and more advanced tests, related to the circumstances that place a proj 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.
