| 摘 要： | 标准贯入试验是现场测定土体工程性质的重要原位试验,是现场快速判定土体密实度的重要依据,具有及时、可靠、经济等特点,在地质勘察中被广泛的应用。本文通过介绍标准贯入试验的基本原理和设备,比较了英国规范、美国ASTM规范和我国岩土工程勘察规范之间标准贯入试验的差异,介绍了标准贯入试验所适用的经验公式,结合在美国ASTM规范指导下具体的工程实践结果,应用标准贯入试验的结果分析了苏丹国尼罗河Dagash流域内的土体工程性质,对比钻探所得土样和袖珍贯入测力计试验结果,验证了标贯结果的正确性。

| Abstract: | Standard penetration test is an important in-situ test for the determination of engineering properties of soil,and an important basis for the quick determination of soil compactness on site Between the United States ASTM specification and the geology technical engineering specification standard penetration test,standard penetration test is introduced which is the experience formula of combination in the United States ASTM specification under the guidance of specific engineering practice as a result,the results of standard penetration test is used to analyze the sultanate Dagash the Nile river basin within the engineering properties of soil,the contrast of drilling,soil samples and the pocket injection dynamometer test results,verify the validity of the standard penetration results. |
