ABSTRACT

This study examines the impact of large-section rectangular pipe jacking construction on existing structures through the establishment of a three-dimensional model using MIDAS-GTS finite element software. The simulation analyzes surface deformation and displacement characteristics during construction. Results indicate that pipe jacking construction causes significant disturbances to the surface and surrounding structures, primarily resulting in soil settlement. The deformation range expands progressively as construction advances. By optimizing construction parameters such as grouting pressure and volume, the study effectively reduces surface settlement and structural displacement, providing valuable insights for similar engineering projects.
