Provides additional information on box culverts design and installation in relation to AS 1597.2.

Although the primary use of the box culverts is for carrying water, the application of this Standard's requirements to box culverts used for other purposes such as pedestrian or vehicular underpasses, escape or reclaim tunnels or earth-retaining structures is considered to be acceptable. The limit on culvert dimensions of length, height and span are set only to give acceptable boundaries for the work of the Committee. The design of culvert units with larger dimensions may be carried out using the principles given in Section 3 or Section 4 provided that the designer has adequately addressed the effects of increased dimension on load and structural responses. Particular care should be exercised in the adoption of equivalent loadings which may not be suitable for culverts larger than 4200 mm span and 4200 mm leg height. Each special culvert should be individually designed for its unique condition. Where large holes are required in a unit, the remaining cross-section should be designed to resist the total bending moment and shear applied to the culvert. A similar approach should be adopted for a skewed unit in combination with the relevant provisions of this Standard. The maximum height of fill is limited to 10 m since the effect of soil arching in deep fills has not been considered when determining loads on the culvert. This simplification will result in a conservative result in high fill situations, however the degree of conservatism was considered acceptable by the Committee for fills up to 10 m.
