摘要

快速冲击压实(RIC)，有时也被称为快速动态压实(RDC)，近年来在沙特阿拉伯的大型战略项目中使用显著增加，主要是由于大量的时间和成本节约效益。根据动态压实的概念，RIC机器已开发用于路基压实和6米深的浅层处理，通过提供压实锤连接到液压挖掘机的强化臂。本文基于数值模型结果支持的实验测量结果，得出了防止RIC对相邻建筑物和埋地公用设施造成潜在损害所需的最小安全距离。

Vibration Induced By Rapid Impact Compaction on Granular Soils

The use of Rapid Impact Compaction (RIC), sometimes referred as Rapid Dynamic Compaction (RDC), has increased significantly in the latest years in Saudi Arabia mainly for large scale and strategic projects due to substantial time and cost saving benefits. Following the concept of Dynamic Compaction, RIC machines have been developed for the compaction of embankments and shallow treatment up to 6m depth, by providing a compaction hammer attached to a strengthened arm of a hydraulic excavator. This paper concludes the minimum required safe distance to prevent any potential damages of RIC on adjacent buildings and buried utilities, based on the results of experimental measurements supported by numerical model results.
