摘要
强夯法是将重锤以一定的落距自由落下给地基以冲击和振动,使地基出现强大的应力波,引起土体内密度、应力、孔隙水压力等的变化,从而达到提高地基强度的目的。由于强夯法具有加固效果显著,施工设备简单,施工迅速和工程造价低廉等优点,其广泛应用于大面积、大块石高填方地基。分析了传统分层碾压施工方法处理块石高填方地基的局限性,结合工程实例,介绍了强夯法在处理大块石高填方地基时的施工要点,结果表明该方法能缩短工期、节约成本。
Dynamic consolidation is to make the heavy hammer falls free down to the foundation at a given distance where the impacts and vibration are formed to make the powerful stress wave,cause the variation of internal stress in soil mass and pressure of void water,and achieve the improvement of foundation strength.This method has the merits of remarkable effect for strengthening,simple equipment for construction,fast construction and low price,which is widely used in high-filled foundation with large area and large stones.The limitation of bedded-earth rolling method treating high-filled foundation with stones is introduced.Based on the practical project,the construction main points of dynamic consolidation method treating high-filled foundation with large stones are present.Results show that dynamic consolidation method can shorten construction period and save cost.
