碎石土回填铁路路基强夯试验研究

Research on Dynamic Compaction Test of Railway Bed Backfilled with Crushed Stone Soil

对碎石土回填铁路路基强夯工程,开展孔隙水压力、变形监测及测量,研究强夯对碎石土路基的夯点间距、影响深度、最佳夯击次数等相关参数,结合研究结果,得出用于指导本工程地基处理大面积施工参数,同时供本地区类似工程项目的设计与施工借鉴和参考。

The pore water pressure and ground deformation are monitored and measured in the dynamic compaction project of railway bed backfilled with crushed stone soil. Some parameters obtained during the dynamic compaction are studied, i.e. the spacing between two tamping points, impact depth and the optimum tamping times etc. The research results produce the large-size construction parameters for guiding the foundation treatment of the project, which may serve as references for the design and construction of local projects.
