摘要
To systematically study the impact of deep foundation pit excavation on adjacent existing rail structure and electric tower, we can take targeted deformation control measures and ensure the safety of the surrounding environment. Based on the engineering examples and considering the double hardening characteristics of soil, a three-dimensional fine-grained dynamic and static model of foundation pit + roadbed + viaduct + pylon was built to analyze the influence of foundation pit excavation on the track and the high-voltage tower and put forward targeted deformation control measures. Finally, a comparative analysis and demonstration were conducted with the monitoring results of the whole process of on-site construction. Many useful conclusions have been drawn. The study can provide guidance for the design and construction of this project, and also provide a reference for similar projects.
