| Abstract: | This paper establishes the calculation model of three dimensional elastic plasticity of road-bridge transitional section simulates moving load of running vehicles and analyzes differential settlement of pavements with light solidified flyash backfills and silty clay backfills adjacent to abutment under the effect of running vehicle load.The result indicates that the pavement with light solidified flyash backfills can effectively reduce differential settlement adjacent to abutment. |
