  3. In order to resolve the problem from waterproof for underground storage cavern, a comprehensive control measure composed mainly of water drainage with water cutoff and block up as the supplement is followed in the construction, in which the countermeasures such as drain - guiding with piping network, water proof with impervious slab, self - waterproof of concrete structures, jointing waterproof and painting waterproof etc. are adopted, and then a better effect is got in the engineering practice concerned

    摘要為解決好地下洞庫的防水問題，施工中遵循「以排為主，截、堵、排相結合的綜合治理措施」 ，採用了管網引排、防水板防水、混凝土結構自防水、接縫防水、塗料防水等防水作法，經工程實踐取得了良好效果。
  4. Construction of plastic concrete impervious core in chaole water complex

    綽勒水利樞紐塑性混凝土防滲墻的施工
  5. Another hidden danger is the weakening of the impervious ability of the dam resulting from the closeness of the height of line seepage of the reservoir water level to the contact plane between the residual solum, talus solum and basement rocks

    水庫水位浸潤線標高和殘坡積土與基巖接觸界面標高較接近，而使此高程的防滲能力更加薄弱，這也是此壩體的隱患之一。
  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。
  7. 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
  8. The resulting landscape is dominated by impervious surfaces ? parking lots, roads, sidewalks, rooftops and construction sites compacted by heavy equipment ? that do not let water soak through

    最後形成的景觀就是由不透水的地面所主宰停車場、道路、人行道、屋頂，以及由重型機械壓實的建築工地，水都無法滲入這些地方。
  9. The result shows that the profile of the main dam and the second dam and all the impervious rock fill material have no problem. the total seepage volume is 3. 9092x106m3 per year. it occupies 0. 037 % of the average inflow of the reservoir, which is acceptable from the point of view of the water resources utilization

    分析結果：確定採用的主、副壩壩剖面及各種築壩料在滲透穩定性方面均無問題；全壩滲漏總量為390 . 92萬m ~ 3年，佔多年平均入庫水量的0 . 037 ，從水資源利用的角度是可以接受的。
  10. Rubber boots are impervious to water

    橡膠鞋是防水的。
  11. As its working condition is underwater 120 ~ 175m in the three - gorges area, it utilizes the displacement technology and deep - water impervious technology to meet the higher requirements in terms of water - tightness, corrosion resistance and operation reliability

    由於它的工作環境為三峽壩區水下120 175米，所以該系統採用了位移傳感技術與深水防滲技術以滿足在水密性、耐腐蝕性和工作可靠性等各方面的較高要求。
  12. Article 42 at places where no satisfactory impervious strata exist, enterprises and institutions shall be forbidden to use ditches, pits or ponds devoid of safeguards against seepage for conveyance or storage of waste water containing toxic pollutants or pathogens, or of other wastes

    第四十二條在無良好隔滲地層，禁止企業事業單位使用無防止滲漏措施的溝渠、坑塘等輸送或者存貯含有毒污染物的廢水、含病原體的污水和其他廢棄物。
