ʻO nā hiʻohiʻona o ka lepo pale i ka hopena i ka hana anti-filtration. Ke hana nui nei ka geotextile ma ke ʻano he catalyst i ka papa anti-filtration, e hāpai ana i ka hoʻokumu ʻana o kahi papa luna a me kahi papa kānana kūlohelohe i ka upstream o ka geotextile. ʻO ka papa kānana kūlohelohe kahi hana i ka anti-filtration. No laila, he hopena koʻikoʻi nā waiwai o ka lepo pale i nā hiʻohiʻona o ka kānana inverted. Ke like ka nui o ka lepo me ka nui o ka pore o ka geotextile, hiki ke poloka i ka geotextile.

Pāʻani nui nā Geotextiles i ka hana catalytic i ka kānana inverted
Ka nonuniformity coefficient o ka lepo e hoike ana i ka nonuniformity o ka nui o ka nui, a me ka lakio o ka hiʻona pore nui o ka geotextile OF i ka hiʻona nui particle DX o ka lepo e hahai i ka nonuniformity coefficient C μ E hoʻonui a emi iho, a me ka lepo me ka nui o ka nui emi iho. ʻAʻole hiki i ka 0.228OF ke hana i ka papa ma luna 20. E pili ana ke ʻano o nā ʻāpana lepo i nā ʻano paʻa lepo o ka geotextile. Hōʻike ka ʻimi ʻana o ka microscope electron i nā hiʻohiʻona axis lōʻihi a pōkole i nā huelo, kahi e kumu ai ka anisotropy holoʻokoʻa o nā huelo. Eia nō naʻe, ʻaʻohe hopena quantitative maopopo i ka mana o ke ʻano o nā ʻāpana. ʻO ka lepo pale i maʻalahi ke kumu i ka hāʻule ʻole o ka kānana inverted kekahi mau hiʻohiʻona maʻamau.
Pāʻani nui nā Geotextiles i ka hana catalytic i ka kānana inverted
Hoʻokaʻawale ka German Society of Soil Mechanics and Basic Engineering i ka lepo pale i ka lepo pilikia a me ka lepo paʻa. ʻO ka lepo pilikia ka nui o ka lepo me ka lepo kiʻekiʻe, nā ʻāpana maikaʻi a me ka cohesion haʻahaʻa, aia kekahi o kēia mau hiʻohiʻona: ① ʻoi aku ka liʻiliʻi o ka plasticity index ma mua o 15, a i ʻole ka liʻiliʻi o ka pālolo/silt ma lalo o 0.5; ② ʻOi aku ka nui o ka lepo ma waena o 0.02 a me 0.1m ma mua o 50%; ③ Koefficient kūlike ʻole C μ ʻAʻole i ʻoi aku ma mua o 15 a loaʻa nā ʻāpana pālolo a me ka lepo. Ua ʻike ʻia nā ʻikepili o ka nui o nā hihia hōʻino geotextile kānana e pale i ka papa kānana geotextile i kēia mau ʻano lepo e like me ka hiki: ① ʻaʻole hui pū ʻia me ka nui o ka nui; ② ʻAi ʻole ʻia i ka ʻāina haʻihaʻi; ③ E hoʻopuehu ka pālolo hoʻopuehu i nā ʻāpana maikaʻi ʻokoʻa me ka manawa; ④ Nui ka lepo i nā ion hao. Ua manaʻo ka haʻawina ʻo Bhatia ʻo ka paʻa ʻole o ka lepo i kumu ʻole ai ka kānana geotextile. ʻO ka paʻa o loko o ka lepo e pili ana i ka hiki i nā ʻāpana koʻikoʻi ke pale i nā ʻāpana maikaʻi mai ka lawe ʻia ʻana e ka wai. Nui nā pae hoʻohālikelike i hoʻokumu ʻia no ke aʻo ʻana i ka paʻa o loko. Ma o ka nānā ʻana a me ka hōʻoia ʻana o 131 mau pae hoʻohālike maʻamau no nā pūʻulu ʻikepili ʻano ʻāina, ua noi ʻia nā pae hoʻohālike e pili ana.
