Discussion on the Existence of Bedding Fractures under Stratigraphic Conditions Based on the Coupling Relationship between Multi-stage Stress Fields and Clastic Particle Contact

Qi Yalin, Qi Yalin
2025-11-25 ChinaXiv: chinaxiv-202511.00163 Mixed Source

To clarify the existence of foliation fractures (including bedding fractures) under formation conditions in tectonically stable areas of sedimentary basins, reveal the differences between fractures observed in surface cores and real subsurface fracture systems, and guide the exploration of shale-typ…

Postprint: Real-Time Monitoring of Adjacent Construction Impact on Shield Tunnels Based on Dynamic Response of Operating Subway Systems

Li Qi, Xie Xiongyao, Zeng Kun
2025-09-02 ChinaXiv: chinaxiv-202509.00016 Mixed Source

This paper proposes a real-time sensing method based on the dynamic response of an operating metro system to monitor the impact of adjacent construction activities on shield tunnels. The effectiveness of the method is verified through a combination of numerical simulation and model testing. The simu…
