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 1 000 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.
Abstract
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 P5 of about 75.96%,the cohesive force c is 10.64 kPa,and the internal friction angle φ is At26 °.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 1 000 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 still needs to be obtained through experiments.
