Makhalidwe a nthaka yotetezedwa ali ndi mphamvu pa ntchito ya fyuluta inverted.Geotextile makamaka imagwira ntchito ngati chothandizira pazosefera zopindika, zomwe zimapangitsa kuti nthaka yotetezedwa yomwe ili pamwamba pa geotextile ipange chosanjikiza chapamwamba komanso chosanjikiza chachilengedwe.Zosefera zachilengedwe zimakhala ngati fyuluta yotembenuzidwa.Choncho, katundu wa nthaka otetezedwa ndi yofunika kwambiri pa makhalidwe a inverted fyuluta.Ngati tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono ta geotextile, ndiye kuti timatsekeka mkati mwa geotextile.
Kodi ntchito zazikulu za geotextile mu fyuluta yolowera ndi chiyani
Geotextile makamaka imagwira ntchito ngati chothandizira muzosefera zolowetsedwa
Kupanda kufanana kwa nthaka kumasonyeza kusafanana kwa tinthu tating'onoting'ono, ndipo chiŵerengero cha mawonekedwe a geotextile ndi mawonekedwe a tinthu tating'onoting'ono DX a nthaka ayenera kutsatira zomwe sizili zofanana C μ Tinthu tating'onoting'ono tating'onoting'ono zosakwana 0.228OF sizingapange mawonekedwe apamwamba a nthaka yosungiramo particles 20.Kujambula ndi maikulosikopu ya ma elekitironi, kumapezeka kuti michirayo ili ndi mawonekedwe owoneka bwino atali ndi aafupi, omwe amayambitsa anisotropy yonse ya ma tailings, koma palibe chidziwitso chomveka bwino chokhudza kukhudzidwa kwa mawonekedwe a tinthu.Dothi lotetezedwa lomwe ndi losavuta kuyambitsa kulephera kwa fyuluta yolowera ili ndi mawonekedwe ena onse.

German Society of Soil Mechanics and Foundation Engineering imagawa nthaka yotetezedwa kukhala dothi lamavuto ndi nthaka yokhazikika.Dothi lomwe lili ndi vuto makamaka ndi dothi lokhala ndi tinthu tambiri ta silt, tinthu tating'onoting'ono komanso kulumikizana kochepa, komwe kumakhala ndi chimodzi mwazinthu izi: ① index ya pulasitiki ndi yochepera 15, kapena chiŵerengero cha dongo/silt ndi zosakwana 0.5;② Zomwe zili mu dothi lokhala ndi tinthu ting'onoting'ono pakati pa 0.02 ~ 0.1m ndizoposa 50%;③ Coefficient yosiyana C μ Pansi pa 15 ndipo imakhala ndi dongo ndi silt particles.Ziwerengero zamilandu yochuluka ya zosefera za geotextile zinapeza kuti fyuluta ya geotextile iyenera kupewa mitundu iyi ya dothi momwe ingathere: ① dothi losalumikizana bwino la njere ndi kukula kwa tinthu ting'onoting'ono;② Dothi losweka losalumikizana;③ Dongo lobalalika lidzamwazikana kukhala tinthu tating'ono tating'ono pakapita nthawi;④ Nthaka yokhala ndi ayoni yachitsulo.Bhatia amafufuza kuti kusakhazikika kwamkati kwa dothi kumayambitsa kulephera kwa fyuluta ya geotextile.Kukhazikika kwamkati kwa nthaka kumatanthauza kuthekera kwa tinthu tambirimbiri toteteza tinthu tating'ono ting'onoting'ono kuti tisatengeke ndi kutuluka kwa madzi.Njira zambiri zapangidwa kuti ziphunzire kukhazikika kwamkati kwa nthaka.Kupyolera mu kusanthula ndi kutsimikizira kwa 131 njira zofananira za seti zamtundu wa nthaka, njira zambiri zogwiritsiridwa ntchito zaperekedwa.
