Abstract:

Three structural steel plate pipes (SSPP) have been instrumented and tested as part of an extensive culvert research program by the California Department of Transportation. Two were functional roadway cross drains, at Chadd Creek and Apple Canyon, and one was a grossly underdesigned culvert, the DB culvert. The Chadd Creek culvert was a 114-in. SSPP 0.280 in. thick with 89 ft of overfill and Method B backfill (baled straw surmounting the pipe). The diagram of Method B fill height versus soil stress was nonlinear; strains and strain gradients were large; deflection was 1 percent. The Apple Canyon culvert was a twin 108-in. SSPP 0.375 in. thick with 160 ft of overfill and Method A backfill (structure backfill surrounding the culvert periphery). The diagram of Method A fill height versus soil stress was linear; relatively uniform peripheral pressures were observed; there was an effective density increase of 50 percent subsequent to fill completion and 2 percent deflection. The DB culvert was a 120-in. SSPP 0.109 in. thick with a maximum of 190 ft of overfill and six zones of Method A backfill and two zones of Method B backfill. The six Method A zones suffered excessive deflections or seam failure before fill completion. The two Method B zones (with slotted bolt holes or sprayed polystyrene backpacking) reduced effective densities significantly. Conclusions for Method A are that the design loading should be 140V:140H and that the effective density increase should be 1.5. The Marston and Spangler design methods are not recommended; ring-compression and neutral-point analysis are acceptable designs. The Method B conclusions are that baled straw is not recommended and that slotted bolt holes and sprayed polystyrene show promise.
