Gully erosion, which is universal on original lands, but also the special forms, for example, hole erosion gravel erosion debris slide and debris flow, which is unusual in loess area, ( 2 ) based on a long - term fixed point experiments in proving ground of the south stackpile, the soil erosion factors have been researched quantitatively, the runoff and erosion affected factors have been made sure and the experiential models of producing water and soil have been taken in newly - constructed stage, early stage and later stage of reclamation
確定南排土場原地貌的水蝕模數為3700 4400t km ~ 2 ? a ；在排土場新造地貌上，擊濺、面蝕、細溝侵蝕、淺溝侵蝕、沉陷侵蝕、砂礫化面蝕、土砂瀉溜和坡面泥石流等水土流失形式出現頻率和發生程度都明顯強于原地貌。 （ 2 ）以南排土場徑流試驗場長期的定位觀測為基礎，對排土場未復墾時期、復墾初期、復墾後期的土壤水蝕影響因子進行定量研究，確定了徑流和土壤水蝕的主要影響因子及其臨界值，建立了產流產沙的經驗模型。 -
The stress condition ; overall stability ; effect of filling gravels into the hole of the block of the precast concrete interlocking blocks in the water flow during the flood period as well as the resistance parameters of the blocks are studied through experimental simulation ; in which a comprehensive analysis is made on the mechanical stability and the anti - erosion properties of the blocks, and then the requirement and the safety degree of the gravel filling are given
摘要通過試驗模擬研究了預制混凝土連鎖塊在洪水期水流中的受力狀況、整體穩定性、孔內填充碎石的作用及連鎖塊阻力參數，綜合分析了連鎖塊結構的力學穩定性和抗沖性，給出了碎石填充的要求及安全度。
