This European Stan

25、dard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2014, and conflicting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of

26、this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1537:1999. The remit of CEN/TC 288 is the standardisation of the execution procedures for geotechnical works (including testi

27、ng and control methods) and of the required material properties. CEN/TC 288/WG 14 has been charged with the revision of EN 1537:1999 in the subject area of ground anchors, which includes all anchors that are bonded to the ground by grout and are stressed and tested. This standard has been prepared t

28、o stand alongside EN 1997-1, Eurocode 7: Geotechnical design Part 1: General rules, and prEN ISO 22477-5, Geotechnical investigation and testing Testing of geotechnical structures Part 5. Design, safety aspects and testing, which were included as the informative Annexes D and E in the previous issue

29、 of this standard (EN 1537:1999), were consequently taken out of this present issue. Clause 7, “Considerations related to design” of this standard deals only with those design matters that should be taken into account during the execution stage of ground anchors so that the design of the anchor syst

30、em may be fulfilled. In addition, this standard provides full coverage of the construction and supervision requirements. The revision of this standard was effected by a working group comprising of delegates from ten countries and the comments of these countries have been taken into account. The main

31、 amendments are: definitions and terminology brought into accordance with the definitions and terminology of EN 1997-1:2004, Eurocode 7, in particular with Section 8; alignment of this European Standard with prEN ISO 22477-5; structural revisions to match the structure of this standard with that of

32、other standards for special geotechnical works, e.g. EN 1536, Execution of special geotechnical work Bored piles and EN 1538, Execution of special geotechnical work Diaphragm walls; general revision in accordance with comments received during the CEN Enquiry, 2010; update of references. As long as E

33、N ISO 22477-5 is not available, national solutions should be implemented for the testing of anchors. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,

34、Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the Un

35、ited Kingdom. DIN EN 1537:2014-07 EN 1537:2013 (E) 5 1 Scope 1.1 This European Standard covers ground anchors grouted into the ground which are stressed and tested. They can be used for permanent or temporary applications. NOTE For the purpose of this standard the term anchor(s) refers to ground anc

36、hor(s). 1.2 The anchors are designed in accordance with EN 1997-1 and are tested in accordance with prEN ISO 22477-5. 1.3 Typical bond and compression type anchors are shown in Figure 1 and Figure 2. 1.4 The term “ground“ is taken to encompass soil, rock and fill already in place or existing prior t

37、o the execution of the construction work. 1.5 The planning and design of ground anchors calls for experience and knowledge in this specialised field. 1.6 The installation and testing phases require skilled, qualified labour and supervision. 1.7 This standard cannot replace the knowledge of specialis

38、t personnel and the expertise of experienced contractors required to apply this standard. 1.8 This standard does not address systems such as tension piles, screw anchors, mechanical anchors, soil nails, dead-man anchors or expander anchors as these do not fulfil the requirements of this standard.
