scope:

This Standard specifies structural design methods for buried corrugated metal structures of circular or other shape installed under a flexible pavement.

Buried corrugated metal structures are primarily intended for use in stormwater drainage and access tunnels, and for the support of roadway and railway and other loadings. Construction consists of corrugated section shapes buried in an embankment or in a trench situation. Correct installation in a soil envelope is essential to the performance of the structure.

The design methods in this Standard are intended to apply to the products described in the other parts of this AS/NZS 2041 series with profiles that satisfy the following criteria:

(a) c/p≤8 H

(b)  p/wr≤5

where

p = pitch of corrugation, in millimetres

Hc = height of corrugation rib, in millimetres

wr = width of corrugation rib, in millimetres

These products range from small pipes to large arch-type structures, from off-the-shelf systems to significant long-span structures.

NOTES:

1 Guidelines on information that should be supplied by the designer and/or owner to the manufacturer and installer are given in Appendix A.

2 This Standard is intended to cover buried structures comprising a flexible corrugated metal wall and a soil envelope governed by soil-structure interaction. It must be recognized that both soil and metal structure play a vital part in the structural design; therefore proper installation is essential for the final performance. Background on the Standard material, including the ring compression theory, is given in Appendix B.

3 In order to ensure good performance, general design procedures should include site investigation, backfill material selection, flow design, durability assessment, structural design, handling and laying and, backfill compaction.

4 For non-flexible pavements, specialist advice should be sought.
