The gently tilt-layered shale displays anisotropic behavior and includes structural planes that cause the rock to exhibit weakened features. As a result, load-bearing capacity failure mechanisms of this type differ significantly from those other types. A series uniaxial compression tests were performed on samples Chaoyang Tunnel investigate damage evolution patterns typical characteristics shale. An acoustic emission testing system was incorporated analyze parameters during loading process....

The deformation characteristics and the timing for secondary lining support in high geo-stress soft rock tunnels have drawn significant attention. In carbonaceous shale formations, tunnel construction deformations are very pronounced under disturbances due to development of joints, dense fractures, poor interlayer bonding. With Xishuangbanna as our research backdrop, this study meticulously analyzed patterns inherent constructed within schist formations. Employing a comprehensive approach...

Travel data containing personal identification information needs to be anonymized before being shared and analyzed for privacy considerations. In a multi-modal transport system with different operators covering one segment of the market collecting their own customers’ travel data, it is typically difficult identify trajectory same traveler across these modes (e.g. bikes, metro, bus). This has been main hurdle understanding complete trip chains door-to-door patterns. To address this...

Influenced by the anisotropy and water-softening characteristics of gently inclined layered shale, many tunnels have encountered bottom deformation issues during construction operation, which severely impact safety tunnel structures. The energy evolution law rock damage can provide support for assessment prediction structure deformation. However, most studies been conducted on enstatite, granite, sandstone with limited research shale. In this study, both conventional single-cyclic...
