Abstract: At present, more research had been done on the indoor model test of the influence of soft soil circular tunnel construction on adjacent structures. However, the indoor model test for the deformation of adjacent underground pipelines caused by the excavation of quasi-rectangular-irregular section tunnel was still rare to study. Based on the quasi-rectangular-shaped section tunnel excavation convergence displacement mode, a model test system for the deformation of adjacent underground pipelines induced by quasi-rectangular tunnel excavation was established, including quasi-rectangular tunnel excavation simulation device, pipeline simulation device, pipeline displacement measurement system, and model test data collection system, etc. The excavation process of quasi-rectangular tunnel was simulated by four liquid bags drainage, and the settlement deformation of adjacent underground pipelines, the internal force of pipeline section, and the surface contact force of excavation-like tunnel excavation and the earth pressure of pipeline surface were recorded in real time. Tunnel excavation induced settlement deformation of adjacent underground pipelines and internal force distribution and development of pipeline sections. It was found that the settlement value of pipelines increased slowly with the drainage of tunnel sacs, and the soil pressure on the surface of tunnels and pipelines increased slowly and then stabilized. In addition, a variety of working condition model tests were carried out for different pipeline depths and pipeline outer diameters. The results showed that under the same working conditions of pipeline outer diameter, as the pipeline depth increased, the distance between the tunnel and the pipeline became smaller, as the settlement deformation of the pipeline increased, the internal force of the pipeline increased. Under the same working conditions of the buried depth of the pipeline, as the outer diameter of the pipeline increased, the settlement deformation of the pipeline decreased, and the internal force of the pipeline increased. At the same time, the numerical model of the corresponding working conditions was established and compared with the model test results, and good consistency was obtained.
