J. Cent. South Univ. (2021) 28: 1519-1533 DOI: https://doi.org/10.1007/s11771-021-4703-0 Centrifugal and field studies on water infiltration characteristics below canals under wetting-drying...) and wetting-drying-freezing-thawing (WDFT) cycles were performed to investigate the water infiltration characteristics below a canal. The results show that the shallow soil of the canal models was fully......
Influences of material dilatancy and pore water pressure on stability factor of shallow tunnels YANG Xiao-li(杨小礼), HUANG Fu(黄 阜) School of Civil and Architectural Engineering, Central... support in limit state. The proposed method was formulated within the nonassociative plasticity. For the shallow tunnels in soft clay, without considering the influences of pore water pressure......
