| 摘 要： | 针对某沿海地区机场跑道的软基加固处理工程,采用了"塑料排水板+强夯+冲击碾压"相结合的联合处理方案。"塑料排水板+强夯"对地面下2～8m范围内软基加固有较明显效果,但是在地面下2m范围内由于强夯扰动土体,加固效果不明显。故在强夯后采用冲击碾压法,以提高浅层土体的强度与刚度。处理后的测试结果表明"塑料排水板+强夯+冲击碾压"处理方案对加固饱和软土地基效果良好。

| Abstract: | Aiming at strengthening the treatment of the soft ground of the runway of a certain airport in the coastal area,the combined technical scheme of＂plastic drain＋dynamic compaction＋impact compactio＂n is applied for the project.It is found that the technical scheme of＂plastic drain＋dynamic compaction＂is effective for soft ground reinforcement in the range of 2～8 munderground,but its effect is not obvious in the range of 2munderground as a result of the disturbance of the dynamic compaction.Therefore,the impact compaction is performed after the completion of the dynamic compaction in order to improve the strength and stiffness of the shallow soil.The post-treatment result of the soft soil shows that the combined technical scheme of＂plastic drain＋dynamic compaction＋impact compaction＂is effective in strengthening the saturated soft ground. |
