自然坡 meaning in English
depositional gradient
Examples
- This paper studies the perturbation action of celestial bodies ' movement on the earth from the view of celestial mechanics , and furthermore analyzes the effect of celestial bodies ' movement on the natural slope stability due to phosphorus ore mining in mountainous areas
摘要针对宜昌磷矿高陡山区地下开采对上部山体稳定性影响，从天体力学的角度探讨天体运动对地球的摄动作用，并分析月球运动的引力对山区磷矿自然坡失稳的影响。 - With synthesize slope ratio increasing , the stability of cutting slopes decreases , but the stability of sharpen slope affected by natural slopes ratio changes rarely , the stability of cutting slope that height is 30m is change notably due to slope type , whose single slope ratio with madao is inferior to the slope that upper ratio is less than lower ratio with platform in middle part . but the stability of cutting slope with 50m height is little change with the slope type change . with same stratum , slope height , slope type , the cutting slope is inferior to the sharpen slope in stability
结果表明，地层含水量在12 . 0 18 . 0变化范围内，各种挖方边坡稳定性均随湿度的增大而显著降低；路堑边坡的稳定性随综合坡比的增大而降低，但削坡受自然坡比影响，随综合坡比的增大其稳定性基本不变；坡高30m的路堑边坡稳定性因坡型改变而有明显变化，且单一坡比多级马道型边坡的稳定性较上缓下陡平台型边坡的稳定性差，但坡高50m的路堑边坡稳定性因坡型变化而基本不变；当坡高、坡型、地层条件相同时，路堑边坡的稳定性较削坡的稳定性差。
