“…The Plaxis 3D tunnel software is used to simulate the shield mechanized tunneling process, including applying face pressure, grouting and lining installation. This software uses nite element analysis (FEM) to model the ground and tunnel behavior [32]. Since the tunnel is characterized by a symmetrical geometry, only half of the tunnel was modeled.…”

Tunnel construction in the urban area is often a challenge due to the presence of masonry buildings. The aim of this study is to investigate the effects of the geometric characteristics of masonry buildings, on the damage caused by tunneling using numerical simulations. The results show that the width of the building is a more important factor in controlling settlement and damage to the building than its length. The analysis of the building's deformation parameters shows that the differential settlements play a greater role in damage to building. Buildings with a width of less than 10 m suffer only minor damage due to small changes in differential settlement. For buildings with a width of more than 10 m and up to 35 m, the differential settlements increase considerably and cause structural damage. The analysis shows that as the width of the building increases, mainly due to a decrease in the stiffness of the foundation, the slope and angular distortion of the foundation increase and consequently the building damage increases. Buildings with a width of less than 10 m suffered only minor damage, while buildings with a width of more than 21 m suffered structural damage. Furthermore, the tilt of the building alone is not a good parameter for assessing building damage. The length of the building has no significant influence on building damage.

“…To ensure the safety and serviceability of the existing pipelines, some researchers have systematically studied the mechanical behaviours of existing pipelines. The researchers commonly used field measurements [1][2][3][4][5], laboratory test methods [6][7][8], numerical simulations [9][10][11], and analytical methods.…”

Spatiotemporal Deformation of Existing Pipeline Due to New Shield Tunnelling Parallel Beneath Considering Construction Process

et al. 2022

In this paper, we study the effects of the shield tunnel construction on the deformation of an existing pipeline parallel to and above the new shield tunnel. We propose an analytical solution to predict the spatiotemporal deformation of the existing pipeline and consider different force patterns of the shield tunnelling, i.e., ground volume loss, support pressure, frictional force, and torsional force. The proposed method is validated by the monitoring data of Subway Line 3 of Nanchang and provides a reasonable estimation of the pipeline’s deformation. The parametric analyses are performed to study the influences on the pipeline’s deformation. The main advantage of our paper is that the spatiotemporal characteristics of the existing pipeline’s deformation are analysed, providing longitudinal deformation curve (LDC), deformation development curve (DDC), and grouting reinforcement curve (GRC). Compared with the perpendicular undercrossing project, both LDC and DDC have the same profiles and maximum values and move forward as a whole with the shield tunnel advance. Thus, the spatiotemporal deformation of the overall pipeline can be extrapolated from the deformation of two known points on the pipeline. The spatiotemporal characteristic curves combined with LDC, DDC, and GRC can suggest feasible, effective, and economical construction and grouting schemes to control the pipeline’s deformation after the deformation control standards have been determined.
