Hunhu hwevhu rakadzivirirwa hune simba pakuita kweinverted filter. Iyo geotextile inonyanya kuita senge inokonzeresa mune inverted sefa layer, ichiita kuti ivhu rakachengetedzwa riri kumusoro kwegeotextile rigadzire dhizaini repamusoro uye sefa yakasikwa. Iyo yakasikwa sefa layer inoita sefirita yakapidigurwa. Nokudaro, zvinhu zvevhu rakadzivirirwa zvine simba rinokosha pamaitiro e-inverted filter. Kana iyo ivhu chidimbu saizi yakaenzana nedhayamita yepore ye geotextile, inogona kunge yakavharika mukati meiyo geotextile.
Ndeapi mabasa makuru e geotextile mune inverted sefa
Iyo geotextile inonyanya kuita senge catalyst mune inverted sefa
Iyo isiri-uniformity coefficient yevhu inoratidza kusafanana kwekukura kwechidimbu, uye reshiyo yehunhu hwekuvhura OF ye geotextile kune hunhu diki saizi DX yevhu inofanirwa kutevedzera isiri-uniformity coefficient C μ Zvimedu zvevhu zvine saizi yechidimbu. isingasviki 0.228OF haigoni kuumba denga repamusoro 20. Chimiro chezvikamu zvevhu chichakanganisa maitiro ekuchengetedza ivhu re geotextile. Kutarisa ne electron maikorosikopu, zvinoonekwa kuti miswe yacho ine hunhu hwakareba uye hupfupi hweakisi, izvo zvinokonzeresa anisotropy yese yemiswe, asi hapana mhedziso yehuwandu hwakajeka pane pesvedzero yechimiro chechidimbu. Iyo ivhu rakadzivirirwa iro riri nyore kukonzera kutadza kweiyo inverted sefa ine mamwe maitiro akajairika.

The German Society of Soil Mechanics uye Foundation Engineering inokamura ivhu rakachengetedzwa kuva dambudziko ivhu uye yakagadzikana ivhu. Dambudziko revhu rinonyanya ivhu rine zvidimbu zvesilt zvakawanda, zvinyoro zvishoma uye kuwirirana kwakaderera, kune chimwe chezvinhu zvinotevera: ① plasticity index iri pasi pe15, kana clay / silt content ratio iri pasi pe0.5; ② Zviri mukati mevhu rine particle size pakati pe 0.02 ~ 0.1m inodarika 50%; ③ Coefficient isina kuenzana C μ isingasviki gumi neshanu uye ine ivhu uye silt zvidimbu. Huwandu hwehuwandu hukuru hwegeotextile sefa yekutadza kesi dzakaona kuti geotextile sefa inofanirwa kudzivirira marudzi anotevera evhu nepazvinobvira: ① isina kubatanidzwa ivhu rakatsetseka rakakodzwa rine saizi imwechete; ② Ivhu rakaputsika rakakoshwa rakabatana; ③ Ivhu rinoparadzira richapararira kuita zvidimbu zvakapfava nekufamba kwenguva; ④ Ivhu rakapfuma mune iron ions. Bhatia anodzidza kuti kusagadzikana kwemukati kwevhu kunokonzera kutadza kwegeotextile sefa. Kudzikama kwemukati mevhu (internal stability) zvinoreva kugona kwezvidimbu zvakakasharara kudzivirira kuti zvidimbu zvinyoro zvisatakurwe nekuyerera kwemvura. Mazhinji maitiro akaumbwa ekudzidza kwekugadzikana kwemukati mevhu. Kuburikidza nekuongorora uye kuoneswa kwe131 yakajairika maitiro eivhu hunhu hwe data seti, mamwe maitiro anoshanda akatsanangurwa.
