【摘要】 某高速公路软粘土与可液化砂土互层地基用加强型袋装砂井进行处理,但标准贯入试验检测结果显示此方法对可液化砂层的挤密效果不明显。用瞬态面波勘察方法对其进行检测,通过面波速度、面波波速剖面影像图、平均剪切波速、平均动剪切模量等方面的结果分析,发现此处理方法有一定效果。由此也说明瞬态面波勘察方法可以在软基处理检测方面应用。更多还原

【Abstract】 In order to improve the liquidation sand and silt crossbedded foundation synthetically in a highway,the improved sand bag wells have been used.As the checked and measured result of the Standard Penetration Test(SPT)wasn’t notable,the transient state surface wave was fetched into checking and measuring the improved effect.By contrastively analyzing the surface wave velocity,the profile image of the wave velocity,the average shear wave velocity and the average dynamic shear modulus,the effect of the improved sand bag wells was notable to some extent.So the method of the transient state surface wave can be applied in checking and measuring silt foundation.更多还原
