Ukusetshenziswa kwe-geogrid yensimbi-yepulasitiki ekuqiniseni nasekukhuliseni i-subgrade

1. Isimiso sokuqinisa

• Thuthukisa ukuzinza kwenhlabathi
  • Amandla okudonseka kwe-geogrid yensimbi-yepulasitiki athwalwa yintambo yensimbi enamandla aphezulu elukiwe nge-warp kanye ne-weft, ekhiqiza i-modulus yokudonseka ephezulu kakhulu ngaphansi komthamo ophansi wokucindezeleka. Umphumela wokubambisana wezimbambo ezinde neziphambeneyo unganikeza ukusebenza okugcwele kumphumela wokukhiya wegridi enhlabathini, uvimbele ngempumelelo ukufuduka kwenhlabathi eceleni futhi kuthuthukise ukuzinza okuphelele kwe-subgrade. Kufana nokwengeza uhlaka oluqinile enhlabathini ekhululekile, ukuze inhlabathi ingabi lula ukuyishintsha.
• Umthamo wokuthwala umthwalo othuthukisiwe
  • Ukugoba kanye nokugoba kwezintambo zensimbi zezimbambo ezinde neziphambeneyo kuthungwa kube inethi, futhi ungqimba lokugoqa lwangaphandle lwenziwa ngesikhathi esisodwa. Ucingo lwensimbi kanye nongqimba lokugoqa lwangaphandle lungahlangana, futhi ukunwebeka kokuhluleka kuphansi kakhulu (hhayi ngaphezu kuka-3%). Iyunithi yokucindezeleka eyinhloko ucingo lwensimbi, kanti ukugoba kuphansi kakhulu. Izici ezinjalo zivumela i-geogrid yensimbi-yepulasitiki ukuthi ithwale amandla amakhulu okudonswa ku-subgrade, yabelane ngengcindezi yezimoto neminye imithwalo ku-subgrade, ngaleyo ndlela ithuthukise amandla okuthwala we-subgrade, njengokwengeza amaphuzu amaningi okusekela aqinile ku-subgrade ebuthakathaka 。
• Khulisa i-coefficient yokungqubuzana
  • Ngokusebenzisa indlela yokwelapha ubuso bepulasitiki enqubweni yokukhiqiza, amaphethini aqinile ayacindezelwa, okuthuthukisa ubulukhuni bobuso begridi futhi kuthuthukise i-coefficient yokungqubuzana phakathi kwegridi yensimbi-yepulasitiki nomhlabathi. Lokhu kusiza ukubopha kangcono igridi nomhlabathi, okuvumela igridi ukuthi idlale indima yokuqinisa ephumelela kakhulu futhi ivimbele ukuguguleka ekusheleleni ngaphansi komthwalo.

2. Ukusetshenziswa okuqondile ekuqiniseni nasekukhuliseni i-subgrade

• Ukusetshenziswa kokuhlangana kwe-subgrade entsha nendala
  • Nciphisa ukuxazululwa okungalingani：Kuphrojekthi yokwandiswa nokwakhiwa kabusha kwemigwaqo emidala, kulula ukuhlangana ngokungalingani lapho kuhlangana khona umbhede omusha nomdala. I-geogrid yensimbi-yepulasitiki inamandla amakhulu okudonseka, ebekwe phakathi kombhede omusha nomdala, ingathuthukisa ukuzinza kombhede lapho kuhlangana khona imigwaqo emisha neyakudala, inciphise noma ivimbele ngempumelelo isimo sokuqhekeka okubangelwa ukuhlukaniswa ngokungalingani kombhede wemigwaqo emisha neyakudala, yenze imigwaqo emisha neyakudala yakheke yonke, iqinisekise ukuzinza kombhede wemigwaqo。
  • Ukuxhumana okuthuthukisiwe：Ingaxhumanisa kangcono inhlabathi ye-subgrade entsha nenhlabathi ye-subgrade endala, ukuze i-subgrade entsha neyakudala ikwazi ukuthwala amandla ndawonye. Isibonelo, lapho umgwaqo omdala unwetshwa, i-geogrid yensimbi-yepulasitiki ibekwa ezingeni lokuhlangana komgwaqo omusha nowakudala, futhi izimbambo zayo ezinde nezivundlile zingavalwa ngokuqinile nenhlabathi ezinhlangothini zombili, ukuze kuthuthukiswe amandla okuthwala kanye nokuqina komgwaqo omusha nowakudala, futhi kuvinjelwe izinkinga ezifana nokuqhekeka noma ukuwohloka ngesikhathi sokusetshenziswa okulandelayo。
• Ingxenye enwebekayo yokuqinisa i-subgrade
  • Amandla okugunda athuthukisiwe：Kwi-subgrade enwetshiwe, i-geogrid yensimbi-yepulasitiki ingathuthukisa amandla okucheba enhlabathi enwetshiwe. Lapho i-subgrade ibhekene namandla avundlile njengokushayela imoto, i-grille ingamelana naleli gunya lokucheba elivundlile futhi ivimbele ukwehluleka kokucheba kwenhlabathi enwetshiwe. Isibonelo, kumaphrojekthi okunweba umgwaqo omkhulu, ukubeka i-geogrid yensimbi-yepulasitiki ekugcwalisweni kwe-subgrade enwetshiwe kungathuthukisa kakhulu ukumelana kokucheba kwe-subgrade futhi kuqinisekise ukuphepha nokuzinza kwesakhiwo se-subgrade enwetshiwe。
  • Ukuvimbela ukufuduka kwe-lateralNgenxa yokusebenza kahle kokuthambekela kwe-geogrid yensimbi-yepulasitiki, ingavimbela ngempumelelo ukuguqulwa kwe-lateral kokugcwaliswa kwe-subgrade. Ngesikhathi senqubo yokwakha yokwandisa i-subgrade, inhlabathi yokugcwalisa ingasuswa iye ngaphandle ngaphansi kwesenzo sokuzithwala kanye nomthwalo wangaphandle. I-geogrid yensimbi-yepulasitiki inganikeza ukuvimbela kwe-lateral, igcine isimo nosayizi we-subgrade, futhi igweme ukuwohloka kwe-subgrade.
