【摘要】 分析了Menard公式修正法中折减系数的变化特点,探讨了一些影响强夯加固深度的因素,应用相似理论方法建立了强夯加固深度的相似准则,由此给出了估算强夯地基加固深度的公式.计算分析结果表明,该式把夯能与土的阻抗耗能结合起来,不仅可考虑夯能大小问题,而且可考虑土类土性问题、锤径影响问题,能取得很好效果.更多还原

【Abstract】 This paper discussed the features of revision coefficient in the revised influence depth formula (given) by L.Menard for different kinds of soils,and analyzed some factors affecting the effective depth of dynamic compaction.A similarity rule was established by the application of similarity theory,thus giving a new formula to estimate the depth.It is demonstrated by the satisfying calculating results that considering tamping energy as well as consumption of energy for soil impedance in the new equation makes it possible that not only the amount of tamping energy can be taken into account,but also natures of soils and diameters of hammers can be (researched.)更多还原
