This paper presents a method of tamping for improving unconsolidated sand and gravel foundation backfilled on the flood land,and introduces the principles of soil improvement with some engineering cases.
首次提出了对河漫滩上抛掷回填松散砂卵石地基采用重锤夯实法进行加固，介绍了加固的原理及工程实例，并结合工程实例通过现场试验论证了它为一种技术可靠、经济合理、施工可行的方案，为今后在松散砂卵石地基中应用这一方法提供了可靠依据。
Connecting with the practices of treatments of the soft roadbed, this paper introduces several common treatment methods of soft roadbed, including soil replacement cushion method, tamping method, vibroflotation method and high-pressure rotary method.
结合软土地基处理工程实践经验,介绍了目前比较常用的几种处理软弱地基的方法,包括排淤或换土垫层法、重锤夯实法、振冲法和高压旋转法。
The primary consolidation settlement of saturated soft clay has finished under static loading of fill soil treating with drainage consolidation; and the surface fill soil was dynamically compacted by tamping method.
介绍了利用重锤夯实法加固表层填土与排水固结法加固深层软土联合处理库内层状软土地基的方法,在填土静荷载和塑料排水板作用下淤泥质软土很快完成主固结沉降,重锤夯实法使表层填土受到动力压密,软土和填土强度得以提高。
