ʻO nā hiʻohiʻona o ka lepo i hoʻomaluʻia he hopena i ka hana o ka kānana hoʻohuli. Hana nui ka geotextile ma ke ʻano he catalyst i ka papa kānana inverted, e koi ana i ka lepo i pale ʻia i luna o ka geotextile e hana i kahi papa luna a me kahi papa kānana kūlohelohe. Hana ʻia ka papa kānana kūlohelohe e like me ke kānana inverted. 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 ke anawaena pore o ka geotextile, hiki ke ālai ʻia i loko o ka geotextile.
He aha nā hana nui o ka geotextile i ka kānana inverted
Hana nui ka geotextile ma ke ʻano he catalyst i ka kānana inverted
ʻO ka helu like ʻole o ka lepo e hōʻike ana i ka like ʻole o ka nui o ka nui, a ʻo ka lakio o ka ʻano aperture OF o ka geotextile i ke ʻano o ka nui DX o ka lepo e hahai i ka coefficient like ʻole C μ ʻO nā ʻāpana lepo me ka nui o ka lepo. ʻaʻole hiki i ka 0.228OF ke hana i ka papa luna 20. E pili ana ke ʻano o nā ʻāpana lepo i nā ʻano mālama mālama lepo o ka geotextile. ʻO ka nānā ʻana me ka microscope electron, ʻike ʻia aia nā hiʻohiʻona axis lōʻihi a pōkole i nā huelo, ʻo ia ke kumu o ka anisotropy holoʻokoʻa o nā huelo, akā ʻaʻohe hopena quantitative maopopo i ka mana o ke ʻano o ka ʻāpana. ʻO ka lepo pale i maʻalahi ke kumu i ka hāʻule ʻole o ka kānana inverted kekahi mau hiʻohiʻona maʻamau.
Hana nui ka geotextile ma ke ʻano he catalyst i ka kānana inverted
Hoʻokaʻawale ka German Society of Soil Mechanics and Foundation 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 nui o nā ʻāpana lepo, nā ʻāpana maikaʻi a me ka cohesion haʻahaʻa, aia kekahi o kēia mau ʻano: ① ʻoi aku ka nui o ka helu plasticity ma mua o 15, a i ʻole ka pālolo / lepo ma lalo o 0.5; ② ʻOi aku ka nui o ka lepo ma waena o 0.02~0.1m 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 hoʻoheheʻe geotextile e pale aku i ka kānana geotextile i nā ʻano lepo e like me ka hiki loa: ① ʻaʻole i hui pū ʻia me ka nui o ka ʻāpana; ② Haʻihaʻi ʻia ka lepo cohesionless; ③ E lūlū ʻia ka pālolo hoʻopuehu i loko o nā ʻāpana maikaʻi i kēlā me kēia manawa; ④ Nui ka lepo i nā ion hao. Ke noiʻi nei ʻo Bhatia ʻo ka paʻa ʻole o loko o ka lepo ke kumu i ka hemahema o 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 ʻimi ʻana a me ka hōʻoia ʻana o 131 mau pae hoʻohālike maʻamau no nā pūʻulu ʻikepili ʻano lepo, ua manaʻo ʻia nā pae hoʻohālike e pili ana.
