Vibration model test and seismic performance evaluation of polypropylene fiber reinforced concrete lining of mountainside tunnels in Loess Plateau

Abstract Currently, tunnels are key infrastructure projects for traversing the Loess Plateau and ensuring rail connectivity. However, seismic damage surveys indicate that tunnels built along mountainsides in the Loess region suffer severe damage during earthquakes due to their lo...

Gradient‐Mass‐Transfer Synthesis of 2D [Bi 2 CuO 3 ]SO 4 Crystals for Anisotropy Engineering

ABSTRACT The intrinsic physical anisotropy of low‐symmetry materials makes them highly promising candidates for polarization‐sensitive devices. However, their practical application remains constrained by the scarcity of single materials that can combine low symmetry with high per...

Methods for evaluating the seismic isolation performance of foam concrete shock-absorbing layers in mountain tunnels in high-seismic-intensity areas

Abstract Currently, a large number of post-earthquake surveys and statistical analyses of tunnel damage indicate that tunnels built against mountainsides are subject to the coupled effects of “asymmetric loads and seismic cyclic action,” which increase the risk of earthquake-indu...
