滲濾系數 的英文怎麼說
中文拼音 [shènlǜxìshǔ]
滲濾系數
英文
coefficient of percolation-
( 4 ) the maximum water quantity becomes greater, the better is the filtering bed permeability, the higher the river hydraulic conductance, the higher the river level, the larger the water - collecting area and the bigger the distance between collecting pipes. the water quantity varies directly with drawdown
（ 4 ）濾床的滲透性能越好，河床水力傳導系數越高，河水水位越高，取水面積越大，取水管之間的間距越大，則最大取水量越大；水位降深與取水量成正比關系。In this article the conclusion was got from some experiments and researches that the crux of the matter is to solve the seepage stability of the soil and it is possible that gravelly soil is made into impervious core with the protection of filter
但是存在土料的含礫量不均勻、粘粒含量低、滲透系數偏大、天然含水量偏低、塑性較差等缺陷。試驗研究還認為，只要解決好滲透穩定問題，做好反濾保護，礫質土作心墻防滲體是可行的。Third according to the practice, over 300 g / m2 of the staple nonwoven geotechnical fabric is used in the bank project of the large rivers, its tensile strength is 600 n / 5cm. forth the filtration under the traffic load, normally, the traffic load is repeated load and fast movement. in this case, thick filtration is applied, such as sand and / or thick fabric, of which weight is over 700 g / m2
研究結果表明：對d _ （ 85 ） 0 . 074mm的土料，不宜採用土工織物作濾層；對級配極不均勻的土壤（不均勻系數cu 2或cu 6 ） ，在滲流作用下，很容易發生管涌，對土工織物的選用要慎重；一般大江大河的護坡工程至少應採用300g m ~ 2以上的短纖無紡土工布，其抗拉強度為600n 5cm左右。Standard test method for analytical procedure determining transmissivity, storage coefficient, and anisotropy ratio from a network of partially penetrating wells
測定不完整滲透井網路過濾系數儲藏系數和各向異性比率的標準試驗方法Coefficient of percolation
滲濾系數Abstract : a number of comprehensive study data of cores, structures, inclusions, well - testing performance and fracture pressure gradient have shown that there are several fracture types in the jurassic tight sandstone reserviors of western sichuan basin, such as local structures, subtraction ( load relieving ), stratification and corrosion etc. the leading origin type of fracture is the paleo - subtractive one formed by uplifting subtraction during geohistorical process, which is the main percolation passage in the process of oil / gas concentration, reservoiring and production
文摘:川西侏羅系緻密砂巖儲層中，存在局部構造、卸載、層理及溶蝕等數種裂縫類型，而由地史過程中的隆升卸載作用形成的古卸載裂縫是主導裂縫，也是油氣富集、成藏及產出過程中的主要滲濾通道。分享友人
