1、Designation: A964/A964M 03 (Reapproved 2011)A964/A964M 17Standard Specification forCorrugated Steel Box Culverts1This standard is issued under the fixed designation A964/A964M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the ye
2、ar of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope Scope*1.1 This specification covers material, geometric, and wall section properties of steel box culverts manufact
3、ured fromcorrugated plate or sheet, with or without attached stiffeners, for field assembly. Appropriate fasteners and optional materials suchas steel invert plates and headwalls are also described.Applications for steel box culverts include conduits for gravity flow drainageof surface water such as
4、 culverts and storm drains, as well as for small bridges and grade separation structures such as pedestrianor vehicular underpasses, and utility tunnels.1.2 This specification does not include requirements for foundations, backfill, or the relationship between earth cover or liveloads and strength r
5、equirements. These important design considerations are described in the AASHTO LRFD Bridge DesignSpecifications, Customary U.S. Units (LRFD Bridge Design Specifications, SI Units).1.3 This specification does not include requirements for the hydraulic design of these structures. Hydraulic design, pla
