SOIL STRESSES AND DISPLACEMENTS IN A CONCRETE PIPE TRENCH INSTALLATION

The field performance of a full-scale reinforced concrete pipe in a trench installation is described. Total normal stresses were measured by specially designed stress cells placed in the soil and at the soil-pipe interface. Relative displacements between the pipe wall and various discrete points in the soil immediately adjacent to the pipe were determined by means of settlement plates with stems extending through sleeves into the pipe. Stresses and relative displacements, as well as horizontal and vertical diameter changes, were monitored periodically as the height of cover above the pipe increased. In general, the experimental measurements are mutually consistent and compatible with previous experience and judgment; however, there are some differences between the experimental data and the results calculated from a plane strain, finite element model with appropriate soil parameters.
