Bridge-head bumping processing method for relatively deep mud soft soil foundation behind abutment
The invention discloses a bridge-head bumping processing method for a relatively deep mud soft soil foundation behind an abutment. The bridge-head bumping processing method comprises a step of firstly arranging a bridge-head transition slab at a position behind the abutment and simultaneously performing road structural layer construction on the road below the bridge-head transition slab. The method further comprises the steps of laying a dry jet mixing pile layer below the bridge-head transition slab along the extension direction of a road; and after laying of the dry jet mixing pile layer is finished, laying a graded broken stone unit layer on the pile top of the dry jet mixing pile layer in the length range of the bridge-head transition slab; wherein a plurality of steel-plastic composite geogrid layers are sandwiched in the graded broken stone unit layer; and a cement stable broken stone layer is laid between the top layer of the graded broken stone unit layer and the bridge-head transition slab. The bridge-head bumping processing method has functions of effectively settling a bridge-head settlement problem at the relatively deep mud soft soil foundation behind the abutment, effectively reducing number of times of bridge-head bumping at the head end behind the abutment, preventing bridge-head bumping at the tail end behind the abutment, realizing high comfort and high stability in driving to the pavement behind the abutment, and greatly improving safety on a driving pavement.
