谷缘 meaning in English
valley margin
Examples
- The cure measures are mainly to cut the top of loess slope , to drain terrene water , and so on
治理措施主要是合理处理人工谷缘和排除地表水等。 - The results indicate that the stability of the landfall reduces with the increase of gradient of it . furthermore , the landfall is only stable when its gradient is no bigger than its natural gradient ( 40 ? 45 ? . 3
计算结果表明：宅基边坡伤亡性黄土崩塌的稳定性随谷缘坡体坡度的增大而降低；当其坡度不大于自然坡度（ 40 45 ）时，此类崩塌方能处于稳定状态。 - It is testified that the landfall happens because of the increase in shearing stress and tensile stress . the mechanism and main prevention - cure measure of cutting the top of loess slope according to its nature gradient for the landfall are quantitatively reformed and simulated
模拟再现了陕北宅基边坡伤亡性黄土崩塌的形成机制，验证了治理此类崩塌的有效措施?建成的宅基边坡谷缘坡度不得大于天然谷缘坡度。 - There are two main innovate ideas in the dissertation . ( 1 ) supported by the results from the method of limit analysis of soil plasticity and the ultimate equity method , the author proposes the criterion of judging of stability of slope of foundation of a building
本文的创新点主要有：采用塑性极限分析和极限平衡方法，通过计算，提出了黄土地区宅基边坡的稳定性评价标准，即人工谷缘的坡度不得大于天然坡度。 - On the basis of the geomechanical model for slope deformation and destruction , the developmental process of this landfall is divided into four stages , which are valley - side margin ripping , margin slope creeping , the short slip belt being formed and pierced , and the landfall befallen
通过宅基边坡伤亡性黄土崩塌变形破坏的地质力学模式分析，将此类崩塌分为斜坡谷缘拉裂?谷缘坡体蠕动?短滑带形成并贯通?崩塌土体剪出4个阶段。
