本文以位于国道212线甘肃化马泥石流为例,基于多年来的现场观察及室内电镜分析,比较深入地研究了蠕动性泥石流的显微结构及显微构造特征.结果表明,蠕动性泥石流的微结构有杂基支撑结构、颗粒支撑结构、整体结构及筛状结构;微构造主要包括滑动构造、滑坡构造、翻卷构造、显微层状构造、擦槽、裂缝构造、绕流构造、粘块现象、块状构造等类型.蠕动性泥石流是介于滑坡和泥石流之间的一种过度性灾害地质地貌过程.
In this paper, taking the Debris Flow in Gansu Huamashan, located on State Route 212 as an example, the microstructures and microstructural features of creep debris flow are studied in depth based on the field observation and indoor electron microscope analysis over the years. The results show that the microstructure of creep debris flow is heterogeneous support structure, particle support structure, monolithic structure and sieve-like structure. Microfabrication mainly includes sliding structure, landslide structure, rolling structure, microscopic layered structure, wiping groove and crack structure , Flow around the structure, sticky block phenomenon, block structure and other types. Creep debris flow is between landslides and debris flow of an over-disastrous geological landscape.
