摘要：A model experiment is carried out in this study by using plexiglass rod to simulate the concrete pile and PVC pipe to simulate the underground pipeline, in order to analyze the impact of concrete pile soil squeezing effect on the deformation of underground pipelines. The results show that the pipeline exhibits a strain softening phenomenon during the pile driving process when the pile-to-pipeline distance is relatively small, and the pipeline strain tends to stabilize when the pile-to-pipeline distance is relatively large. In general, as the pile driving process continues, the strain of the underground pipeline increases gradually; the deeper the pipeline, the larger the strain is. However, when the pile-to-pipeline distance is relatively large, the pipeline strain decreases with the increase of the buried depth; the larger the pile-to- pipeline distance, the smaller the strain is. This experiment has an important value in guiding the design and construction of pile foundation engineering projects in complex environments.
