“…The reason is that an additional soil cover of 3D significantly contributes to the lower soil pressure at the pipe crown because more soil is available for load sharing (Arockiasamy et al, 2006). Figs.…”

“…They found that the soil density and the pipe embedded depth would be the most important factors affecting the soil-pipe interaction. Arockiasamy et al (2006) performed field tests on polyethylene, PVC, and metallic large-diameter pipes subjected to highway design truck loading. The field test results indicated that the buried flexible pipes, embedded with highly compacted sand with silt, demonstrated good performance without exhibiting any visible joint opening or structural distress.…”

“…In recent years, the damage phenomenon of urban road surface of underground pipe is serious, especially the ruin of shallow buried pipeline, which greatly affects the smoothness and safety of urban traffic. In order to ensure the normal operation of pipelines, many scholars have studied the stress, deformation, settlement, and cracking of underground pipe [1][2][3][4][5][6].…”

To obtain the optimal load-reduction scheme and calculation method of earth pressure on the crown of the pipe, the load-reduction efficiency of rigid pipe and flexible pipe with different thicknesses and layers of expanded polystyrene (EPS) is investigated by model tests, and the law of load reduction is obtained by analyzing the earth pressure and the displacements of the filling around the pipe. The test results show that the earth pressure is obviously reduced with EPS laying on the crown of pipe, and the load-reduction efficiency is increased to be constant with increasing of EPS thickness. In the case that the summation thickness of EPS is constant, the load-reduction efficiency of EPS with two layers spread on the pipe is higher than that of one layer only. Compared with the rigid pipe, the load-reducing effect of flexible pipe is more significant. Based on the data obtained from the model tests, the nonlinear earth pressure calculation formula obtained from regression analysis is adopted, and the results from it are compared with the existing formula consequences of the earth pressure on the buried pipe. The results show that the earth pressure calculated by nonlinear earth pressure theory is on the brink of that tested in the field. The research results can provide references for selection of load-reduction measures and calculation of earth pressure on the crown of the pipe.
