Abstract To address the challenges of low recognition accuracy, robustness, and detection efficiency in existing tunnel face joint fissure methods, we present a deep learning segmentation algorithm called mask region convolutional neural network (Mask R‐CNN) that is enhanced by an advanced Transformer attention mechanism deformable convolution R‐CNN‐TD). The improves backbone network's ability to extract image features focusing on important areas. A enables more precisely conform...
The moisture content is closely related to the shear creep deformation behavior of soft rock, and linear rock can be described by classical Nishihara model. However, its accuracy in describing accelerated nonlinear characteristics effects still needs improved. innovation this paper propose an improved model that describe whole process shale with different content. uses a strain-triggered sticky pot proposes damage factor reflect effect on rock. relationship between exponential function,...
Notched beam specimens were loaded by the three-point bending test device, and effects of different volume contents combinations steel fibers on tensile properties hybrid fiber–reinforced self-compacting concrete (HSFRSCC) studied. The failure law strain field distribution studied digital image correlation (DIC) technology. Moreover, curves between load crack mouth opening displacement (CMOD) 18 groups obtained, stress–strain derived from load–CMOD curves. results show that both single can...
It's inevitable that, various types of construction works emerge within proximity during the large-scale urban rail transit, thus posing huge challenges for actual construction. In this paper, a minute study on risk control shield tunneling beneath existing railroads relying practical engineering is conducted, thereby developing set feasible risk-handling ideas, mainly including: (1) based detailed investigation and analysis background environment, to find out key indicators; (2) carry...
