  1. Power intake dam section foundation impervious curtain grouting in the dachaoshan hydropower plant

    大朝山水電站進水口壩段壩基防滲帷幕灌漿施工
  2. Design and construction of dam foundation impervious curtain grouting for dachaoshan hydropower station

    大朝山水電站大壩基礎防滲帷幕灌漿設計與施工
  3. Boring, grouting and finally forming an impervious curtain in the rock mass with cracks, that is one of the most popular methods of the foundation seepage control at hydraulic and hydroelectric engineering

    採用鉆孔水泥灌漿封堵巖體中的縫隙而形成阻水帷幕，達到減少滲漏量和降低滲透壓力的目的，是水利水電工程基礎處理的重要手段之一。
  4. Through analyzing the seepage observation data of huangtankou concrete gravity dam, foundation seepage behavior are reasonably evaluated. the reason of seepage force rising of individual monolith is impervious elements " flaw and drain holes " block. 4

    分析黃壇口大壩壩基滲流監測資料，正確評價了壩基防滲排水系統的工作狀態，指出了個別壩段滲透壓力升高是由於壩基防滲帷幕缺陷和排水孔被堵造成，為工程加固提供了科學依據。
  5. For example, after the collapse of ditong dam in idaho, may 5, 1976, it was found that it was not impervious very well, the impervious curtain was built poorly. when the seepage went through the impervious curtain, the exit water from the pervious material of the downstream or the right side of dam through the foundation or certain line between the foundation and the dam caused contact scour and piping

    如美國愛得華州提堂壩於1976年5月5日潰決，事後調查分析，因壩基透水性大，防滲帷幕施工質量差，滲流穿透帷幕，經地基或地基與壩的接觸面從壩體下游側透水料區逸出或從右壩肩繞滲經下游壩體逸出，出逸的水流引起了接觸沖刷和管涌，導致潰壩。
  6. The condition of water pressure acting on the both sides of cement - soil retaining wall is researched by computing the seepage field around the wall. it is illustrated that the coefficient of water pressure, which isn ' t constant along the height, is affected seriously by some factors, e. g., the distribution and relative hydraulic permeability of the soil beside the wall, the hydraulic permeability of its foundation, and the buried depth of the impervious layer. as a whole, the lateral pressure acting on the wall based on seepage is always smaller than that without regard to seepage in the non - excavated zone. moreover, the pressure based on seepage is greater than that without regard to seepage in the excavated zone if the coefficient of passive pressure is smaller than 1. 176. this case is of great advantage to the stability of the wall

    通過計算水泥土擋土墻周圍的滲流場，研究了墻側水壓力的變化規律.結果表明：水壓力系數沿高程並非常數，且受到墻側土層分佈及其相對透水性、墻基土的透水性和下臥不透水層埋深等因素的嚴重影響.總體來說，考慮滲流時墻后的側壓力總小於不考慮滲流時的相應值，且當墻前的被動土壓力系數較小時，考慮滲流時該側的側壓力則大於不考慮滲流時的相應值，因此，這種情況有利於擋土墻的穩定
