摘要
标准贯入试验是最常用的原位测试手段之一。在岩土工程勘察中,判定砂土的密实度、确定其地基承载力、判定饱和砂土的液化时均需采用标准贯入试验。在实际工程地质勘察中,如何正确运用标准贯入试验成果显得尤为重要。本文结合作者多年的工程地质实践活动,就标准贯入试验成果在砂土中的应用进行归纳整理,以便为岩土工程勘察服务。
The Standard Penetration Test is the most commonly used means of in situ tests. In geotechnical engineering investigation, the determination of the density of sand, their bearing capacity, and the liquefaction of saturated sand are necessary using standard penetration test. In practice geological prospecting works, how to correctly apply the results of standard penetration test is especially important. The author, on the results of standard penetration test in sand collate, analyze the application to geotechnical engineering investigation services.
