| 摘 要： | 采用冲击碾压技术对高填方路基进行冲压补强,测试分析路基在冲击碾压作用下相关力学参数的变化,以确定更优化的相关施工参数:主要考虑了冲压遍数对路基沉降变形、路基不同深度处压实度、路基填料最大干密度及整体强度的影响.结果表明:随碾压遍数的增加,路基沉降量增加,其增量曲线趋于收敛;碾压20～25遍可以起到对路基较好补强的作用,... |

| Abstract: | Adopting the impact compaction technology to reinforcing a high embankment,and testing and analysising the relevant mechanical parameters under impacting,the optimization construction parameters,the main consideration of the influence of impact times to the settlement of subgrade,compactness at different depths,dry density of filler and overall stability,were determined.The results indicated that the settlement increased as the impacting time raising,and the incremental curve tended to convergence.When the ... |
