| 摘 要： | 襄樊岘山垭地区膨胀土滑坡是影响公路交通的重大地质病害。曾投入了大量资金进行整治均没有收到良好效果。在探明岘山垭膨胀土滑坡的一些重要性质基础上，利用X射线衍射仪（XRD）、X射线荧光光谱（XRF）分析仪和扫描电子显微镜（SEM），综合常规物理力学实验，对滑坡膨胀土物理性质、微观结构进行了深入研究。以此为基础，探讨了该区膨胀土一些特性在滑坡形成演化中的作用，进一步阐明了该滑坡的形成机制，总结了膨胀土滑坡的一些重要规律，对于深入研究膨胀土滑坡及滑坡整治有十分重要的意义。

| Abstract: | The swell soil landslide in Xianshanya area, Xiangfan, Hubei Province, is disastrous on the traffic. Plenty of funds have been invested to solve the problem but have not produced any good result. This is perhaps mainly due to the lack of understanding of the swell soil. Based on some characters of the landslide, the X-ray diffraction (XRD) and X-ray fluorescent (XRF) spectrum and scan electron microscope (SEM) are used to study the physical properties and the microstructure of the swell soil of landslide. Then, the effect of some characters in the formation and evolvement of the swell soil landslide is discussed with more illustration of the landslide formation mechanism. Meanwhile, some important rules of the swell soil of landslide are summed up combined with this area's geological conditions. This may serve as some references for the prevention in the swell soil area. |
