湿陷性黄土路基的处理技术

Treatment Technology of Collapsible Loess Subgrade

用强夯法处理湿陷性黄土的技术,其压缩波使土的孔隙水压力增大,同时土粒错位,土体骨架解体,而随后的剪切波使土颗粒处于更密实的状态,最终能使土的承载力得到有效改善。

When dynamic compaction method is used to dispose collapsible loess, the pressure wave increases the pore water pressure of soil, meanwhile the soil particles displace, the soil body framework is disintegrated and the soil particles become more close-grained by the effect of succedent shear wave. Finally the bearing capacity of soil is improved effectively.
