| 摘 要： | 各种钻探方法对粉细砂层原始状态的影响不一,获得的标贯N值有一定差异。冲击钻对粉细砂层原始状态的影响较大,获得的标贯N值与实际相差较大,而回转钻对粉细砂层原始状态的影响较小,获得的标贯N值与实际比较接近。

| Abstract: | Each kind of boring method has the different effect on the original state of silty sand,so the standard penetration test value N obtained are certainly different.Percussion boring has a large effect on the original state of silty sand,the standard penetration test values N obtained are more different with the practical.Whereas auger boring has a small effect on it,the standard penetration test value Nobtained are closer with the practical. |
