  1. It is suggested that the impervious wall combined with curtain grouting should be taken as the main vertical impervious body for seepage control, and that the full use of slope wash and fully weathered zone as horizontal impervious blanket should be taken to reduce work load for seepage control

    建議採取截滲墻結合帷幕灌漿作垂直防滲體為主的防滲措施，同時充分利用坡積土和全風化帶作為水平防滲鋪蓋以減少防滲處理工作量。
  2. 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
  3. 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
  4. 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。
  5. Gin is the abbreviation for grouting intensity number. it is showed by the product of the final grouting pressure p ( unit : mpa ) on the grouting section and the grouting volume v ( unit : l / m ) on every one meter of the grouting section, which means the energy consumed on every one meter of grouting section. according to gin method, if during the grouting construction, same energy is consumed on every grouting section, i. e. gin keeps to be a constant, an approximately uniform impervious curtain can be obtained

    Gin （ groutingintensitynumber ）即灌漿強度值，它用灌漿孔段上最終的灌漿壓力p （ mpa ）和單位灌漿段長度漿液灌注量v （ l / m ）的乘積表示，其含義為單位灌漿段上消耗的能量， gin法灌漿認為在灌漿施工中，保持各灌漿孔段上消耗一致的能量，即保持gin為常數，便可形成一道大致均勻的防滲帷幕。
  6. 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。
