摘要
强夯施工是将重锤从高处自由落下给地基以冲击力和振动,从而提高地基土的强度并降低其压缩性,改善地基土抗震液化的能力和消除土的湿陷性。本文以辽河石佛寺水库拦河主坝为研究实例,论述了基于无粘性土坝基强夯施工的强夯试验、施工工艺及检测手段和方法.
Dynamic consolidation construction is letting the heavy hammer freely falling from higher place to add the force and pressure on foundation , to increase the strength of foundation soil and decrease its compressibility , and to improve its ability of anti-earthquake liquefaction and clear off collapsibility of soil. In this paper , the authors took the dam of Shifusi Reservoir in Liaohe River as an example , discussed the dynamic consolidation test , construction technology , test and measure means and method on the basis of dynamic consolidation construction for dam foundation of cohesionless soil .
