| 摘 要： | 以昆明～嵩明高速公路后窗子坡面泥石流为例,采用X射线衍射仪对泥石流物源进行矿物成分分析,得知后窗子坡面泥石流体富含高岭石和蒙脱石等亲水性黏土矿物;通过室内模型试验分析后窗子坡面泥石流形成机制,从坡面泥石流形态和裂纹阶段扩展将后窗子坡面泥石流形成过程划分为强度衰减(微裂纹滑移生核)、蠕动变形(微观裂纹扩展)、局部滑动(宏...

| Abstract: | Taking the Houchuangzi slope debris flow along Kunming-Songming Expressway as instance,the mineral composition of provenance on the slope debris flow is analyzed adopted polycrystal X ray diffractometer,which is rich in hydrophilic clay minerals such as kaolinite and montmorillnite;the fornation mechanism of the Houchuangzi slope debris flow is analyzed by the laboratory model test,the fornation process of the Houchuangzi slope debris flow is compartmentalized into five stage from the aspectsof slope debris... |
