| 摘 要： | 通过大量土工试验,对鹤(岗)—大(连)公路路基草炭土密度、含水量与天然孔隙比及压缩系数进行相关性研究,发现草炭土密度与天然含水量存在较好的幂函数关系;密度与天然孔隙比及压缩系数存在较好的指数函数关系;含水量与天然孔隙比及压缩系数均存在很好的指数关系。通过对比发现,各参数之间的相关关系与理论公式吻合较好。比较吉林省其他地区草炭土物理力学指标的相关关系,均与鹤大草炭土显示出很好的相似性。结果表明:本文所建立的草炭土密度、含水量分别与天然孔隙比、压缩系数的相关关系,可以为吉林地区草炭土地基参数计算及预测提供重要参考。

| Abstract: | Through a large number of geotechnical tests,the correlativity between density,water content,natural void ratio and compressive coefficient are examined on the roadbed of the Hegang-Dalian road.It is found that there is a rational power function relationship between density and natural water content.There are also rational exponential relations not only between density and ignition loss but between density and compressive coefficient.In addition,there are fairly good exponential relations not on... |
