摘要 以自行研发室内控制水位之单击试验系统与室内自动圆锥贯入仪,探讨浚填砂土在不同水位受到夯击时,下列各项物理量之差异:①内部激发之动态孔隙水压增量;②有效动态土压力增量;③夯击后之土壤贯入阻抗等。并且引入改良率与贯入功之观念,藉以评估整体之改良效果。结果显示:无水位试体夯击时,在同一深度之有效动态土压力增量远比有水位者为高,且夯击后之土壤贯入阻抗、改良率与贯入功又比有水位者高。同时,低水位试体之夯击成效又比高水位者为佳。 Experimental studies on water single-point impact system developed by level effect for dynamic compaction performance were presented by using the the authors. Meanwhile, an automatic cone penetrometer was also developed to acquire the cone resistance in soil samples. It was indicated that after impaction, the measured increments of excess pore water pressure increased when the water level increased, and the cone resistance (QR) in soils with higher water level was found less than that in soils with lower water level and far less than that measured in dry soils. The terms of improvement ratio (IR) and penetration work (Wq) done were introduced to evaluate the overall performance of improvement.
