Relationship with other publications This Published Document gives non-contradictory complementary information for the design of structures subject to traffic loading for use i
13、n the UK with BS EN 1997-1 for geotechnical design and its UK National Annex. Background is provided to some of the National Annex provisions where these differ from the values recommended in BS EN 1997-1. Presentational conventions The provisions in this Published Document are presented in roman (i
14、.e. upright) type. Its recommendations are expressed in sentences in which the principal auxiliary verb is “should”. Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element. The word “should” is used to express recomme
15、ndations of this Published Document. The word “may” is used in the text to express permissibility, e.g. as an alternative to the primary recommendation of the clause. The word “can” is used to express possibility, e.g. a consequence of an action or an event. Notes and commentaries are provided throu
16、ghout the text of this published document. Notes give references and additional information that are important but do not form part of the recommendations. Commentaries give background information. As a UK Published Document, these presentational conventions are in accordance with BS 0 and national
17、British Standard drafting rules. Therefore, the conventions might differ from the Eurocode that this Published Document supports. Contractual and legal considerations This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct applic
18、ation.

19、design of structures, but in many cases it does not identify specific requirements for particular structure types. This document provides non-contradictory complementary information relating to the design of structures subject to traffic loading to accompany BS EN 1997-1.1 Scope This document covers
20、 some geotechnical aspects of bridges and other structures subject to traffic loading designed to BS EN 1997-1 and other relevant Eurocodes. The document includes information relating to the design of: spread foundations; piled foundations; gravity retaining walls; embedded retaining walls; integral
21、 bridges; and buried concrete structures. It does not cover the design of reinforced soils.2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest editio
