Basa re geogrids mukubata nenheyo dzisina simba rinonyanya kuratidzwa muzvikamu zviviri: kutanga, kuvandudza simba rekutakura kwenheyo, kuderedza kugadzirisa, uye kuwedzera kugadzikana kwenheyo; Chechipiri ndechekusimudzira kutendeseka nekuenderera mberi kwevhu, kudzora zvinobudirira kusagadzikana kwekugara.
Iyo mesh chimiro che geogrid ine inosimbisa mashandiro ayo anoratidzwa neiyo inopindirana simba uye kumisa simba pakati pe geogrid mesh uye zvinhu zvekuzadza. Pasi pechiito chemitoro yakatwasuka, geogrids inoburitsa tensile stress ukuwo ichishandisa lateral kudzora simba pavhu, zvichikonzera kusimba kweshear yakakura uye deformation modulus yevhu rakaumbwa. Panguva imwecheteyo, iyo yakanyanya elastic geogrid inoburitsa yakatwasuka kushushikana mushure mekumanikidzwa, kudzoreredza imwe yemutoro. Mukuwedzera, kugadzika kwevhu pasi pechiito chemutoro wakatwasuka kunokonzera kukwidziridzwa uye lateral displacement yevhu kumativi ose maviri, zvichikonzera kushushikana kwekunetseka pa geogrid uye kudzivirira kusimudza kana lateral displacement yevhu.
Kana hwaro hungasangana nekutadza kweshear, geogrids inodzivirira kutaridzika kwekutadza kwepamusoro uye nekudaro inovandudza kubereka kwenheyo. Kutakura kugona kwegeogrid yakasimbiswa nheyo inoumbwa inogona kuratidzwa neyakareruka fomula:
Pu=CNC+2TSinθ/B+βTNɡ/R
Kubatana kweC-ivhu muchimiro;
NC Foundation inotakura kugona
T-Tensile simba re geogrid
θ - kurerekera kona pakati penheyo kumucheto uye geogrid
B - Pazasi upamhi hwaro
β - Chimiro coefficient yenheyo;
N ɡ - Inoumbwa nheyo inotakura huwandu
R-Yakaenzana deformation yenheyo
Matemu maviri ekupedzisira mufomula anomiririra kuwedzera kubereka kugona kwenheyo nekuda kwekuiswa kwema geogrids.
Iyo inosanganiswa inoumbwa negeogrid uye yekuzadza zvinhu ine kuomarara kwakasiyana kubva pamupendero uye yakaderera nheyo yakapfava, uye ine simba rakasimba rekugera uye kutendeseka. Iyo geogrid yekuzadza composite yakaenzana nepuratifomu yekutamisa mitoro, iyo inotamisa mutoro wekumisikidza pachayo kune yakaderera nheyo yakapfava, ichiita deformation yenheyo yunifomu. Kunyanya kune yakadzika simende ivhu rinosanganisa murwi wekurapa chikamu, iyo inotakura simba pakati pemirwi inosiyana, uye kumisikidzwa kwezvikamu zvekuchinja kunoita kuti boka rega rega remurwi rishande rakazvimiririra, uye kune zvakare kusawirirana kugarisana pakati pemisha. Pasi peiyi nzira yekurapa, chikuva chekutakura mutoro chinoumbwa negeogrids uye mafirita anoita basa rakakosha mukudzora kusawirirana kugadzikana.
