Abstract:

Three reinforced concrete (RC) arch culverts were field tested. These three culverts were heavily instrumented with Carlson soil stressmeters at the extrados and with internal SR-4 strain gauges. An evaluation was made of the relative behavior of structural sections subjected to two types of structure backfill: (a) method A, which employs compacted structure backfill in contact with the extrados, and (b) method B backfill, which has either a low-modulus inclusion that surmounts the culvert or baled straw that surrounds the arch barrel at the extrados. Among the observations were that effective-density profiles at the extrados differed greatly and unconservatively from assumed design conditions, method A range of loadings were confirmed at 140V:140H and 140V:42H, soil-pressure-overfill functions were essentially linear for method A and nonlinear for method B, correlation was established between the theoretical moment (soil pressures) and experimental moments (strains), effective densities did not increase after fill completion, and excellent foundation conditions are a prerequisite for RC arch design.
