摘要
冲击压实能够显著减少路基的工后沉降,提高路基土的整体强度,有效防止由于路基土质量问题引起的路面早期破坏。通过冲击压实试验研究得知,冲击压实的界限值为冲压18次,冲击压实的有效影响深度为1.5m。
Impact compaction method can reduce the settlement of subgrade after construction, improve the integral strength of subgrade soil and effectively prevent the forepart breakage of pavements caused by the quality problems of subgrade soil. The result of impact compaction tests is that the finitude of impact compaction is 18 times, and the effective depth of impact compaction is 1.5 meters.
