摘要
鉴于黄泛区公路路基路面病害多发情况,依托某高速公路,按规程对现场路基填土采样分别进行了颗粒分析试验、界限含水率试验、承载比(CBR)试验和三轴压缩试验,确定了该类土的颗粒级配、界限含水率、CBR值、粘聚力和内摩擦角,并提出了该类土的压实建议,可为黄泛区公路路基的设计与施工提供参考。
In view of the frequent occurrence of highway subgrade and pavement diseases in the area formerly flooded by the Yellow River,relying on an expressway,the grain size analysis test,the limit moisture content test,the Califonia bearing ratio(CBR)test and the triaxial compression test are carried out on the field subgrade filling samples according to the regulations,and the grain grading,the limit moisture content,the CBR value,the cohesion and the internal friction angle of this kind of soil are determined,and the compaction suggestions for this kind of soil are put forward,so as to provide reference for the design and construction of highway subgrade in the area formerly flooded by the Yellow River.
