Abstract
The distribution of underground pipelines in cities is very complex, and changes in the surrounding environment can easily cause deformation and even crack damage to pipelines, which affects the normal use of existing pipelines. Shield tunneling projects significantly disturb the surrounding environment. With the popularization of subways, it has become important to clarify the deformation of existing pipelines caused by shield tunnel construction. In this study, the existing pipeline was simplified as an Euler–Bernoulli beam placed on a Pasternak foundation beam, and the ground loss, additional thrust, shield shell friction, and additional grouting pressure during the shield tunneling process were considered. An equation was derived to describe the deformation of the existing pipeline caused by shield tunneling obliquely through the pipeline. According to the Foshan-Dongguan Intercity Railway Project, a finite difference model (FDM) and the established equation were used to predict the existing pipeline deformation caused by the tunneling of the shield machine. The results reveal that only a small error existed among the theoretical calculation results, FDM result, and field monitoring data, which validates the proposed equation. When the existing pipeline axis is obliquely intersected with the shield tunnel axis, the maximum settlement position of the pipeline appears at the side close to the tail of the shield machine. The settlement of the existing pipeline increases with the decrease of the distance from the tail of the shield machine, and the decrease of the angle between the pipeline axis and the shield tunnel axis increases the settlement of the existing pipeline. When the pipeline is parallel to the axis of the shield tunnel, the disturbance caused by the shield machine construction to the existing pipeline reaches the maximum. The stiffness of the pipeline greatly influences the deformation of the pipeline.
