黄河独特的水文条件、沉积物的细粒特性 ,以及黄河三角洲地区近年来的半干旱气候条件 ,尤其黄河近年来严重断流导致了黄河三角洲水上平原发育了大量的异常地质现象 ,特殊侵蚀沟槽便是其中之一。根据平面形态侵蚀沟槽可分为线状、树枝状、坑洞状、面状 ,网状及隧道状几种 ;横剖面形态有“U”形、“V”形、梯形或窄缝形。其规模不一 ,小者长数厘米 ,宽深数厘米 ;大者长数十、甚至百余米 ;宽十几米 ,深数十厘米到一米多。沟槽壁上常发育滑塌、流痕或类钟乳等次级构造。
The unique hydrological conditions of the Yellow River, the fine-grained characteristics of sediments, and the semi-arid climatic conditions in the Yellow River Delta in recent years, especially the serious drying-off of the Yellow River in recent years have led to the development of a large number of anomalous geological phenomena in the Yellow River Delta water plains. Is one of them. According to the plane form erosion groove can be divided into linear, dendritic, potholes, surface, mesh and tunnel several; cross-sectional shape of a “U” shape, “V” shape, trapezoidal or narrow slit shape. The size of a small, a few centimeters long, a few centimeters wide and deep; the length of dozens of even the largest, or even more than a hundred meters wide; ten meters wide, tens of centimeters deep to more than a meter. Sliding walls often develop slump, flow marks or the like secondary structure of stalactites.
