Dip slope

中文百科

顺向坡

顺向坡英语:Dip slope),又称倾斜坡倾向坡,是一种地质环境,表示一个波面的沉积堆叠方向,较逆向坡容易发生山崩,常见于遭侵蚀作用的地层(例如,断崖)。

有时候,基于成本的考量,很难完全避开顺向坡。当挖断顺向坡之坡脚时,应以人造边坡(Artificial Slope)或挡土墙或岩锚方式,进行结构补强。且当有安全性顾虑时,不宜使用生态工法。

但是,挡土墙或岩锚等边坡防护,应定时检修维护,不然当其支撑力不足以承载上方地层滑落之应力时,将产生「顺向坡滑动」的现象。

A dip slope is a topographic (geomorphic) surface which slopes in the same direction, and often by the same amount, as the true dip or apparent dip of the underlying strata. A dip slope consists of the upper surface of a resistant layer of rock, often called caprock, that is commonly only slightly lowered and reduced in steepness by erosion. Dip slopes form the backslopes of cuestas, homoclinal ridges, hogbacks, and flatirons. The frontslopes of such ridges consist of either an escarpment, a steep slope, or perhaps even a line of cliffs. Generally, cuestas and homoclinal ridges are asymmetrical in that their dip slopes are less steep than their escarpments. In the case of hogbacks and flatirons, the dip of the rocks is so steep that their dip slope approaches the escarpment in their steepness.
