摘要
在冲积平原、河漫滩等地区进行工程建设,一般根据实际工程情况需要,采用静力触探试验,并配以机钻探、标准贯入试验使用,对工程区地层岩性进行划分,以及确定各类土层的厚度、贯入阻力等,并结合室内相同层位土样的试验研究,利用地区工程经验,评价砂土层密实度、液化、承载力等特性,试验资料分析成果有效、可靠。对工程中运用其操作,提供真实、准确、可靠试验资料具有一定的指导意义。
Static sounding test, adopted in the engineering construction on fluvial plain, flood plain and so on according to actual demand of engineering situations, applies with drilling standard penetration test to divide formation lithology in engineering area as well as determine the thickness and penetration resistance of each kind of soil layers, then evaluate several characteristics of sand soil layer including compactness, liquefaction, and bearing capacity which combines with the indoor experimental research of soil samples in same stratigraphic horizon. The results obtained by analyzing the experimental data are effect and reliable. The summary of former static sounding test by authors is of certain guiding significance for operation of static sounding in project and providing true, accurate and reliable experimental data.
