Paper Title:
Analysis of the Impact of Cracking Old Portland Cement Concrete Pavement to Underground Pipe
  Abstract

Impacting and compacting technology is widely applied for re-built old PCC pavement. However, underground pipe would be influenced by impacting machine to possibly occur fracture. A 3D finite element model was established by ADINA software to analyze distribution of additional stress and displacement upon pipe when machine traveled across different positions of slab. The results indicated that longitudinal compressive stress and vertical displacements at the corner of the slab were larger than those at the longitudinal middle fringe of the slab; the influenced depth of additional stress caused by impacting force was about 2.5m and additional stress decayed quickly with the increasing depth; the maximum soil pressure measured in field was smaller than that in numerical simulation.
