黄河小浪底斜坡变形的“反迭瓦”式构造机制研究
|
摘要
针对小浪底地区斜坡中普遍发育的“反迭瓦”式构造，结合该区的工程地质条件，对其成因机制进行分析。提出“反迭瓦”式构造的形成是由于边坡蠕动变形的结果，并非造成滑坡的原因。
Based on the engineering geological conditions, the forming mechanism of the “over
covered tiltes” structure, widely developed in the Xiao Langdi area of Yellow River, has been
analyzed with the methods of mechanics and geology The results of this study suggest that
the relationship between this peculiar structure and landslide could be summarized as follows:
1 Instead of being the cause of landslide, the “over covered tiles” structure in the Xiao
Langdi area is the result of long term slope creeping caused by slope deformation 2 The
structure in this area was formed under such engineering geological conditions as interlacing of
soft and hard rock stratum, long term creeping deformation of slope 3 Since the “over
covered tiles” structure is a phenomenon caused by long term creeping deformation of slope
in the course of landslide deformation, it could be used to predict and analyze the formimg
mechanics of landslide ln other areas where this structure is developed, if their engineering
geological and hydraulic geological conditions are similar to those in the Xiao Langdi area, the
possibility of creeping landslide should be considered
