| 摘 要： | 临沂膨胀土分布广泛，常常导致建(构)筑物的开裂破坏，如何正确认识膨胀土，是该地区亟待解决的重要课题。通过对临沂市自然地质条件、膨胀土的微观及宏观地质特征分析，提出了临沂膨胀土的地质成因为河流冲积的有力证据。在X射线衍射、X荧光分析、扫描电镜观察以及大量土工试验的基础上，对膨胀土的物质成份、微观结构以及工程特征进行了系统的研究。

| Abstract: | The expansive soil distributes widely in Linyi city, and usually causes the building breakage. How to have a correct understanding of the expansive soil is an important task to be solved urgently in this area. By analyzing geological conditions of nature, micro-structure of expansive soil and macroscopic characteristics, it is concluded that the geological cause of the expansive soil is alluvial. Based on X ray diffraction, X fluorescence, TEM and lots of experiments, the material composition, microstructures and the characteristic of engineering are studied by the numbers. |
