园锥动力触探试验N_(63.5)判别饱和砂土液化问题的研究

Cone Penetration Test N_(63.5) on Determining the Liquefaction of Saturated Sandy Soil

现行建筑抗震设计规范采用标准贯入试验判别砂土液化,在实际工作中,愈是液化场地地层愈是松散、易塌孔,很难清底,应用标准贯入试验很难取得饱和砂土的贯入试验准确数据,通过有关理论的推导计算和实际互作的试验对比,认为应用园锥动力触探试验与标准贯入试验是有一定关联,对判别饱和砂土液化是具一定的参考意义。

Standard penetration test is widely used to discriminate the liquefaction of sandy soil in current building anti-earthquake design. In the actual work, the more liquified, the soil layer is more loose and easily collapses. It is difficult to obtain precise penetration test data of saturated sandy soil by using standard penetration test. Through the theory deduction and test comparison, there is correlation between cone penetration test and standard penetration test, which has definite meaning for discriminating the liquefaction of saturated sandy soil.
