摘　　要：文中对洛阳砂卵石土进行室内试验及现场试验,结果表明,对于含水率约为3.92%、粗粒含量P5约为75.96%的砂卵石土,其黏聚力c为10.64 kPa,内摩擦角φ为26°。依据现场平板载荷试验,研究区的砂卵石地基承载力特征值为1000 kPa。由于含水率、颗粒级配以及试验条件存在差异,文中研究获取的砂卵石土相关特征可用于工程应用或研究,但内摩擦角数据仍需通过试验获得。The indoor and on-site test results of Luoyang sand and gravel soil show that for sand and gravel soil with a moisture content of about 3.92%and a coarse particle content of P,of about 75.96%,the cohesive force c is 10.64 kPa,and the internal friction angle is At 26°.According to the on-site plate load test,the characteristic value of the bearing capacity of the sand and gravel foundation in the study area is 1000 kPa.Due to differences in moisture content,particle size distribution,and experimental conditions,most of the sand and gravel soil re-lated characteristics obtained in the study can be used for future engineering applications or research,but internal friction angle data stll needs to be obtained through experiments.
