REINFORCED-CONCRETE PIPE CULVERTS: DESIGN SUMMARY AND IMPLEMENTATION (DISCUSSION)

Research at Mountainhouse Creek and Cross Canyon on reinforced concrete pipe culverts has confirmed the following: (a) loadings 140V:140H and 140V:42H are acceptable for Method A; (b) there is no effective-density increase after fill completion; (c) Method B (baled straw, polystyrene, or uncompacted material) performed well; (d) fill height versus soil pressure is approximately linear for Method A and nonlinear for Method B; (e) there is good correlation between theoretical (soil pressure) and experimental (strain) moments and excellent correlation of the three instrumentation planes placed 3 ft apart; (f) there is asymmetry of loading and moderate success by using Cambridge meters, which measured normal and shear forces on the culvert periphery; (g) adjusted peripheral pressures based on normal and shear forces did not change essential validity of use of normal forces only; and (h) D-loads based on three-edge bearing tests provide valid allowable design overfills. Implementation of this research and future research considerations are discussed. Projected cost savings are $400,000 annually. (Author)
