Abstract
A buried structure. The buried structure includes a pair of structural plates having corrugations extending transversely along a longitudinal direction of the buried structure, and a taper member configured to interconnect, via circumferential taper member edges, the pair of structural plates along respective circumferential structural plate edges. The taper member may have a taper member width progressively decreasing from a first longitudinal taper member edge to a second longitudinal taper member edge. The buried structure thereby configured to extend along the longitudinal direction in a non-linear path based on a separation distance between the adjacent circumferential structural plate edges of the respective structural plates corresponding to the progressively decreasing taper member width. The taper member may be substantially uncorrugated. The taper member may include a plurality of taper plates respectively sized to have taper plate widths progressively decreasing along the taper plate length.
