| 1. | Two test methods are employed : one is loading the samples before thawing , and the other is loading the samples after completely thawed . the coefficient of thaw settlement as a function of granule , as a function of water , and also as a function of dry density are protracted ; besides , the consolidation coefficient of thawed samples as a function of granule , as a function of water , and as a function of dry density are protracted . we can discover from the test results that the thaw - settlement coefficient and the consolidation coefficient of thawed samples are mainly relevant to the granule , dry density and the water content they have little to do with the geology and geography factor of the frozen soils
为了研究季节冻土区工业民用建筑的基础浅埋稳定性问题,特开展了有关季节冻土的融化压缩特性的研究,先后在内蒙古农业大学三个比较典型的建筑地点取了将近三百个试样,在室内进行试验,采取两种试验方法即先融化后压缩试验法和同时融化压缩试验法,通过对这三个不同地点的两种不同的试验方法的试验结果进行对比分行,分别绘制了融沉系数与冻土的含水(冰)量、干容重以及颗粒级配的关系曲线;融化压缩系数与冻土的含水(冰)量、干容重以及颗粒级配的关系曲线,由试验结果发现冻土的融沉系数和融化压缩系数都与冻土的含水量呈正向相关关系,可近似的用线性方程来表示;两种实验方法的总沉降量与冻土的含水量呈正向相关关系,与冻土的干容重呈反向相关关系,也可以近似的用线性方程来表示。 |
