文摘:簡要介紹模袋砂子堤和模袋砼結構的組成及施工工藝等，指出對淺海灘採用此工藝能減小路堤的工后沉降，可收到較好的經濟效益。This paper, applying sequence stratigraphy, through studying on sedimental faices and running the sedimental model, obtained the reservior ' s distributing feature of the whole depression whose centre is the well ou39. this work obtained the distribution scenario of ou39 ' s fan - delta ' s sandbody and the favrable - explorating area to afford the evidences for production
本文應用層序地層學的理論，通過沉積相的研究沉積模式的建立，總結出以歐39井為中心的整個窪子中儲層的展布特徵；通過此工作最終確定出歐39井扇三角洲砂體的分佈情況、勘探的有利區域，為生產提供有利依據。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。To meet the need of settlement calculation with fem when absence of laboratory triaxial test data in common road engineering, methods of determining the five parameters included in tangential elastic module through soil routine tests and the related emendation coefficient are given. at the same time, one approximately substituted formula for tangential poisson ratio is also developed, which is suitable for both sandy soil and cohesive soil.
