LATERAL PRESSURE ON RIGID BRIDGE ABUTMENTS

Current design practice for assessing lateral earth pressures on bridge abutments involves either the use of rule of thumb or classical earth pressure theories. Research carried out over the last two decades has indicated that the actual lateral earth pressures vary considerably from those commonly predicted. A dominating factor in this discrepancy is the effect of lateral pressures induced by compaction plant. This paper presents a simple alternative earth pressure theory which makes some allowance for the effects of compaction. Several case histories are studied and a comparison made between observed pressure distributions and those derived using both current design methods and the alternative theory. The results indicate that conventional design methods render a gross underestimation of bending moments induced in rigid walls and abutments. (TRRL)
