Summary: This study presents three comparative in situ grouting tests for long-term settlement treatment of a cut-and-cover tunnel. The findings suggest that a bottom-up grouting sequence and a cement and water glass grout mixture are more effective for tunnel settlement treatment, providing useful guidance for similar projects.

Summary: This study investigates the changes in soil over time after the construction of high-filled cut-and-cover tunnels in the mountainous Northwest Loess Plateau in China. Results show that discrepancies in soil settlement and surface settlement gradually increase and eventually stabilize, with a redistribution of earth pressure distribution and value. Factors such as slope angle and valley width gradually weaken over time, only affecting the time needed to reach stability.

Summary: A reliability analysis framework for the long-term serviceability assessment of immersed tunnels is proposed, utilizing a novel mathematical model for tunnel settlement analysis. The Bayesian approach and efficient algorithm ensure effective model calibration and uncertainty quantification. The method offers a feasible and effective assessment for improving the reliability and safety of immersed tunnels.

Summary: This study investigates the settlement behavior of metro viaduct piers in soft soil in Shanghai over a period of eight years. The results show that the settlement rate of the piers was highest in the initial years and gradually decreased since 2017. Muddy soil and nearby rivers have a significant impact on the long-term settlement of the piers. Piers located near the river experienced higher settlements, and the influence of the river extended up to 3-4 times its width.

Summary: A systematic method for analysing shield tunnel settlement during the operation period is proposed in this study. A new time-series clustering algorithm called shape-based distance (SBD)-K-medoids is introduced to improve efficiency. The method is validated through a case study of the Shanghai Metro Line 10 (ML10), which demonstrates its rationality and engineering practice value.

Summary: The main goal of this study is to improve the prediction accuracy of ground surface settlements induced by shield tunneling. A comprehensive analysis of long-term ground-displacement data from Metro Lines No. 1 and No. 2 in Changzhou, China was conducted to evaluate the parameters characterizing the settlements. This study can provide a reliable assessment of the long-term and short-term ground surface settlements for tunnel design.

Summary: Insufficient research has been done on the long-term behavior of micropiles embedded in clay, and this paper presents experimental and numerical simulation results on the topic. The study finds that immediate installation of micropiles after the completion of existing floors is successful in controlling the settlement of additional floors.

Summary: This study presents a three-dimensional numerical model based on the Suzhou rail transit line S1 project to evaluate the short-term and long-term displacement caused by shield construction in soft soil strata. The model considers the behavior of soft soil, grouting parameters, and water leakage of the assembled segment lining. Field observations were compared with simulation results, and sensitivity analysis of key parameters was conducted. The results indicate that grouting volume, soft soil thickness under the tunnel, and tunnel leakage conditions significantly affect ground and tunnel settlement.

Summary: This paper presents a novel numerical approach to predict the irregular evolution of railway tracks. The model combines empirical settlement laws with finite element theory to consider train-track interaction and track-soil material behavior. The model is validated and used to demonstrate the importance of frequent geometry updates in accurate predictions. Additionally, a parametric study shows the effect of track subgrade material properties on track settlement.

Summary: This study proposes a model to investigate the long-term behavior of aging tunnels in cohesive soils. The model takes into account the circumferential joint opening and drainage conditions of the tunnel lining. By using coupled soil-water numerical analyses, the model accurately estimates the deformation, load development, and water pressure generation and dissipation in the tunnel over the long term.

Summary: To address the issues of soft and compressible marine soil foundations, an appropriate ground improvement strategy is necessary, and one successful method is reinforcing with stone columns. A field study was conducted along the eastern coast of Australia, using closely spaced stone columns and measuring load-settlement characteristics with sensors. Finite element modeling was used for two-dimensional plane strain analysis, and the numerical results were compared to field data, demonstrating the accuracy of the model.

Summary: The research shows that during tunnel construction under roads at ultra-small distances, a combination of pipe shed and advanced small pipe grouting reinforcement measures can effectively suppress surface settlement, with the reinforcement effect becoming more noticeable after the addition of a larger pipe shed. Additionally, surface settlement caused by excavation of circular soil accounts for 50%-60% of total settlement, making it crucial in the overall construction process.
