延边和龙地区地质特征及地基承载力的研究

Foundation Bearing Capacity and Geological Characteristics of Yanbian Helong

关于延边和龙地区地质特征及地基承载力确定方法的研究较少,通过土工试验,重型动力触探试验和标准贯入试验原位测试方法,分别对和龙地区常在工程中用作持力层的圆砾层和全风化泥岩层的地基承载力进行了测试研究,得到了圆砾层颗粒级配、地基承载力特征值、变形模量的数据,全风化泥岩层地基承载力特征值的数据。对试验数据进行统计分析,得出和龙地区圆砾层地基承载力范围,得出圆砾层地基承载力特征值、变形模量与重型圆锥动力触探锤击数线性相关的结论,以此建立适合当地地质条件的相关经验公式。为延边和龙地区岩土工程勘察工作确保获得可靠、适用的岩土参数提供经验与依据,为周边相似地层的研究提供参考。

Research on foundation bearing capacity and geological characteristics of Yanbian Helong is little, based on geotech- nical test, heavy dynamic penetration test and standard penetration test in situ testing method, Helong area often used gravel layer and weathered mudstone layer in engineering, got round gravel granular layer gradation, foundation bearing force characteristic value, de-formation modulus data, weathered mudstone foundation bearing capacity characteristic value of the data. The test dma for statistical a- nalysis, draw Helong area round gravel layer foundation bearing force and draw round gravel layer foundation bearing force characteris- tic value, deformation modulus and heavy cone dynamic penetration hammer number linearly related to the conclusion, so as to establish the local geological conditions related to the empirical formula, empirical formula. To Helong area geotechnical engineering exploration ensure access to reliable, applied geotechnical parameters provide experience and evidence, provide experience for similar area.
