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。 -
Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers
發展了「土壤水分背景」的概念，並以之為基礎對其各個方面進行了研究，使之形成一個相對獨立和完整的體系，主要包括黃土高原土壤水分的背景值、土壤水分背景的區域分異、坡面分異、鑲嵌結構及其季節分異等： （ 1 ）由於植被生長發展、演替的基礎階段是天然草被群落，故認為黃土高原的土壤水分背景在概念上是特指該區天然草被群落下的土壤水分狀況； （ 2 ）黃土高原的土壤水分背景值，根據植被地帶的不同表現出自南向北逐漸降低的規律：森林地帶3米以下土層水分背景值普遍穩定地高於12 ，森林草原地帶4米以下土層水分背景值穩定大於6 ，且均隨土層的加深水分含量逐漸增加，而草原帶的土壤水分背景值自土表至底土層一直在4 6之間徘徊。 -
By means of the finite element inverse analysis, based on stress - strain theoretical equations of the elastoplasticity and viscoelasticity - viscoplasticity, the change of the valley - side margin stress distribution during original state, the condition of human cutting a terrace of building houses in the loess slope, and the condition of cutting the top of loess slope is elucidated
3 .基於粘彈?粘塑性理論的本構方程，運用有限元方法進行反演分析，闡明了宅基邊坡谷緣在天然條件、斬坡建窯條件下和削坡條件下的應力場變化特點。結果表明，谷緣在斬坡建窯條件下拉張應力和剪切應力增大是導致崩塌產生的根本原因。 -
The ct scanning is ongoing when collapsibility test under triaxial condition of the original loess is conducted. based on combination triaxial collapsibility images with data of scanning, transformation of the microstructure of loess and the mechanism of collapsibility is made clear
進行了三軸試驗條件下原狀黃土濕陷試驗過程中的ct掃描，結合掃描圖像和數據分析闡明了黃土微觀結構變化和濕陷機理。 -
Based on the analysis, the deforming process of the intact loess is divided into three stages because of its special structure. in the first stage, its original structure is intact on the whole
分析得知：原狀黃土由於結構性的影響，其變形可以明顯的分為三個階段：結構基本完好階段、結構破壞階段、重塑階段。 -
( 2 ) the finite element is used to analyze the stress field change of the valley - side margin during original state, the condition of human ' s cutting a terrace of building houses in the loess slope, and the condition of cutting the top of loess slope, then the dynamic mechanism for forming of the landfall is probed
採用有限單元法對宅基邊坡谷緣在天然條件、斬坡建窯條件及削坡處理條件的應力場變化進行了對比分析，揭示了崩塌產生的動力學機制，從而為人工谷緣整治提供了科學依據。 -
