Field measurement and analysis of asymmetric shallow buried twin tunnels with ultra small spacing

Wang Yunlong,Tan Zhongsheng,Chen Ying

Strategic Study of CAE 2012, Volume 14, Issue 11,   Pages 24-28

Abstract:

The ultra-small spacing tunnel of Jiaozhou Bay seabed tunnel in Qingdao is took for example; the surrounding rock pressure features and support force are analyzed through the field measurement. Results show that the surrounding rock pressure and support force of the after-excavation tunnel are larger than others of the tunnel. This result is different from the theoretical predictions and experimental results of most of the small spacing symmetry tunnel. To alleviate these problems effectively, support parameters are adjusted opportunely; the radial support capacity of the after-excavation tunnel is enhanced, and reinforcement measures of rock pillar are made at the same time. The monitoring results show that the stability of the after-construction tunnel has been effectively controlled, which provides useful reference for the design and construction of similar tunnels with small spacing.

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 1,   Pages 11-11 doi: 10.1007/s11465-021-0667-x

Abstract: In the design and troubleshooting of aero-engine pipeline, the vibration reduction of the pipeline systemis often achieved by adjusting the hoop layout, provided that the shape of pipeline remains unchangedHowever, in reality, the pipeline system with the best antivibration performance may be obtained onlyby adjusting the pipeline shape.Based on this, the parametric finite element model of the pipeline system is established.
