Stability of Permeable Flood-Prevention Subgrade Structure under Heavy Rainfal
英文摘要
The steep embankment subgrade of mountain highway becomes one of the severely affected ob-jects, which is damaged by heavy rainfall, because of its poor overall stability and permeability. The new-style flood-prevention permeable subgrade structure formed by reinforced pile-plate gabion retaining wall is put forward and applied in the restoration project of Beijing 7.21 Highway Damaged by floods. The subgrade structure is simulated by ABAQUS software, then its deformation and pore pressure under differ-ent strength of rainfall are analyzed by fluid-solid coupling algorithm, and its stability is analyzed and evaluated by strength reduction method. The results show that the permeable pile-plate gabion retaining wall structure has preferable stability whether before or after the rainfall. Therefore, the reinforced pile-plate gabion retaining wall is one of the preferred flood-prevention permeable retaining structures of mountain highway.
