Mathematical model of determining erosion rate in limestone is studied and some surface erosion rate of limestone are evaluated.
研究了测定灰岩侵蚀速率的数学模型，并且对一些灰岩表面侵蚀速率作了评价。
Subgrade slope surface erosion is defined as a phenomenon which rain runoff destroys subgrade slope surface, and washes away soil on the surface of slope.
路基边坡冲刷是指降雨形成的坡面水流破坏路基边坡坡面，并冲走坡面表层土体的现象。
The surface erosion of expansive soil slope was a kind of common phenomena, so the slope surface protection was an important way to keep the slope stability.
坡面冲刷是膨胀土边坡常见的坡面失稳形式之一，坡面防护对膨胀土边坡的稳定十分重要。
The experiment indicates that wind itself is of weak effect on ground surface erosion, so that the soil crust may not be destroyed even under great wind velocity.
实验表明：净风对土表的风蚀作用微弱，即使在遭到大风吹刮时，土表的结壳仍不易受到破坏。
Surface erosion along the road is about twice as high as the maximum rates reported from the most degraded lands in Southeast Asia.
沿着公路的表面侵蚀率是已报道的东南亚地区退化最为严重的土地最大侵蚀率的两倍。
Surface erosion, surface infiltration and movement of ground water are possible triggering mechanisms of failures in loose filled slopes.
地表水冲蚀与渗入、地下水运动都可能引发松散斜坡破坏。
The deformation modes of high slope in loess highway are mainly slope-surface-erosion and area feature peeling; collapse, slumping and slide could only be seen in some parts of the road section.
公路黄土高边坡的变形破坏形式主要为坡面冲蚀、面状剥落，仅在局部路段见有小型崩塌、滑塌和滑坡。
