摘要
为进一步揭示黄河冲积平原地区粉土工程的特性及其分布规律,对山东省几个较为典型的地区进行土样采集分析,结合工程分类方法,对黄河流域上、中、下游土体进行室内CBR、竖向膨胀率、颗粒分析、XRD。试验结果表明,山东地区黄河冲积平原地区土质以含砂低液限粉土为主,微观组成较为相似,但受水文影响,各地土体砂石料含量不同,体现出黄河水沙变化的复杂性。
To further reveal the engineering characteristics and distribution of silt in the alluvial plain of the Yellow River,the study conducts indoor CBR,vertical expansion rate,particle analysis and XRD on the upper,middle,and lower reaches of the Yellow River Basin by collecting soil samples from several typical areas in Shandong and combining with the existing engineering classification methods.The experimental results show that the soil quality in the alluvial plain of the Yellow River in Shandong is mainly sand-containing low-liquid limit silt,and the microscopic composition is similar,but due to the influence of hydrology,the content of sand and gravel in different soils is different,reflecting the complexity of the water and sand changes of the Yellow River.
