中文摘要：冲击碾压技术是一种高效且低造价的新型浅层地基处理技术,已在国内外公路、机场以及港口等工程的地基加固中得到广泛应用。但是目前关于冲击碾压技术的研究还不多,该技术在浅层地基加固中的适用范围以及加固效果等尚不清楚。通过回顾国内外冲击碾压技术在地基处理方面的应用,总结了该技术在软弱地基、特殊土地基以及其它无粘性土地基处理中的应用现状,并分析了该技术在今后岩土工程实践中的应用前景。

外文摘要：The impact roller (IR) compaction technology is a high- efficient and cost- effective shallow ground improvement technique, which applies high energy to the ground and densifies deeper soils than conventional rollers and plate-type compactors. The IR compaction technology has been widely used for ground improvement in highway, airport, port engineering at home and abroad, but the technology is not well studied at present. How the energy of IR is transferred into soil, the distributions of stress and displacement in soil while impacting, and how the different masses and shapes of impact modules, the characteristics of soil affect the effectiveness of compaction, are still unclear. The scope of application and improvement effect of IR compaction are also not clear. By giving a review of IR compaction used for ground improvement, the application situation of IR compaction technology used for improving soft ground, special soil ground and non- cohesive soil ground has been summarized and the application prospect of IR compaction technology in future geotechnical engineering practice is analyzed.
