Abstract: In order to study the influence of the pile support system on the real mechanical model of the pipe gallery structure, taking an underground comprehensive pipe gallery project in Jinan as an example, the whole process of the project was simulated by using the Plaxis 3D finite element software. It was found that the stress on the side plate of the underground pipe gallery under the pile support was distributed in three sections: first increase, then decrease, then increase, and obviously less than the static earth pressure, and the internal force of the side plate of the pipe gallery was less than the traditional square law. According to the simulation results, the stress distribution curve and its simplified curve of the side plate of the pipe gallery were obtained by changing the thickness of the covered soil on the top of the gallery. The calculation results showed that the internal force of the side plate of the pipe gallery calculated by the simplified curve was in good agreement with the simulation value, that was to say, the simplified curve had better applicability. According to the simplified curve to calculate the side load of the pipe gallery, the designed pipe gallery structure was more practical, economic and reasonable.

Key words: pipe gallery structure, function of supporting structure, earth pressure of backfill soil, deformation of earth, thickness of overburden, force model
