Abstract:
In order to study the variation of larger unbalanced earth pressure of backfill behind abutment caused by vehicle load, several reciprocating low-cycle pseudo-static tests on interaction of soil-abutment-steel H-pile with or without considering the effect of unbalanced earth pressure of backfill behind abutment were carried out. A comparative study was performed to find magnitude, distribution law and calculation method of larger unbalanced earth pressure of backfill behind abutment. The test results indicated that under the test conditions of this paper, with the increase of displacement load, the distribution law of earth pressure for the AHP model changes from "triangle" distribution to "trapezoidal" distribution. The distribution law of earth pressure for the LAHP model is a "trapezoidal" distribution. The earth pressure coefficient for LAHP model is larger than that of AHP model under the reciprocating displacement loading. The test results also indicated that the existing calculation method of earth pressure coefficient is not applicable to IAJBs. The earth pressure coefficient of AHP and LAHP models are significantly larger than active earth pressure coefficient Kac and earth pressure coefficient at rest K0 from the code of General Specifications for Design of Highway Bridges and Culverts (JTG D60-2015) when ∆/H reaches 0.012 (∆/H=0.012). In addition, the earth pressure coefficient for AHP and LAHP models exceed the Coulomb theory when ∆/H reaches 0.012 (∆/H=0.012). They are also larger than the existing theoretical calculation methods.
