Engineering-Level Av Reinforcement Backed by Real Project Experience
Kev ruaj ntseg hauv av tsis yog hais txog kev ua kom muaj peev xwm nce ntxiv - nws yog hais txog kev tswj kev deformation, tswj kev thauj mus los, thiab ua kom ntev - lub sij hawm kev ua tau zoo nyob rau hauv rov qab loading tej yam kev mob.
Los ntawm peb cov kev paub txog kev muab cov yas geogrids rau cov neeg cog lus hauv txoj kev, cov neeg tsim kho vaj tse, thiab cov engineers hauv paus, qhov kev sib tw loj tshaj plaws yog tsis tshua muaj kev xaiv cov khoom siv ib leeg - nws yog qhov kev txhawb nqa cuam tshuam nrog cov av tiag tiag.
Nkag siab qhov teeb meem tiag tiag: Vim li cas Subgrades Fail
Hauv ntau qhov haujlwm peb tau txhawb nqa, kev ua tsis tiav subgrade feem ntau yog los ntawm peb yam ua ke:
Tsawg shear zog ntawm cov av mos Ntau dhau deformation nyob rau hauv load Progressive rutting tshwm sim los ntawm cyclic tsheb thauj khoom
Cov kev daws teeb meem ib txwm muaj (ua kom lub hauv paus tuab lossis siv ntau dua -qib aggregates) feem ntau ua rau:
Cov nqi tsim kho siab dua Lub sijhawm tsim kho ntev dua Tsis paub meej ntev - kev ua tau zoo
👉 Qhov no yog qhov chaw yas geogrid hauv paus hloov cov kev coj cwj pwm.
Kev txhawb zog Mechanism: Tsis yog lub zog xwb, tab sis kev coj tus cwj pwm Hauv cov xwm txheej tiag tiag engineering, yas geogrid tsis ua raws li "load-cov kabmob" ib leeg.mechanically stabilized composite system .
1. Cov nyhuv Confinement Thaum aggregate yog compacted nyob rau hauv lub geogrid, hais tias nkag mus rau hauv lub apertures thiab yog tom qab confined.
Qhov no tsim ib"quasi-txheej txheej" nrog ntau dua modulus tshaj unreinforced av.
👉 Hauv kev soj ntsuam teb, qhov kev kaw no yog thawj qhov laj thawj rau kev txo qis qhov tob.
2. Tensile Membrane nyhuv Nyob rau hauv kev thauj khoom, tshwj xeeb tshaj yog nyob rau hauv cov mos subgrades, lub geogrid tsim tensile rog thiab ua zoo li ib daim nyias nyias.
Qhov no mechanism:
Redistributes ntsug loads
Txo kev ntxhov siab ntawm qhov tsis muaj zog subgrade
👉 Tshwj xeeb zoo thaum CBR <5% (cov av mos heev)
3. Shear Interaction & Interface Friction Lub interface ntawm geogrid thiab aggregate tsim ntxiv shear kuj.
Qhov no txhim kho:
Load hloov efficiency
Stability nyob rau hauv dynamic loads
👉 Hauv cov xwm txheej rov ua dua (piv txwv li, txoj kev loj), qhov no cuam tshuam rau cov txheej txheem degradation.
Design Insight: Dab tsi tiag tiag txiav txim siab kev ua tau zoo
Los ntawm peb qhov kev paub dhau los, peb qhov tsis muaj teeb meem ntau dua li cov neeg yuav khoom feem ntau paub:
Aperture Size vs Aggregate Gradation Yog tias qhov aperture me dhau → tsis muaj kev cuam tshuam
👉 Peb feem ntau pom zoo kom phim aperture loj rau0.5-1.0 × D50 ntawm aggregate
Kev Sib Txuas Zog (feem ntau tsis quav ntsej) Ntau tus neeg muag khoom tsom tsuas yog lub zog tensile, tab sis nyob rau hauv cov xwm txheej tiag tiag:
👉 Junction efficiency txiav txim seb puas muaj peev xwm hloov mus rau hauv kab sib chaws
Tsis muaj zog junctions=thaum ntxov structural tsis ua hauj lwm
Striffness vs Elongation Lub zog tensile siab ib leeg tsis txaus.
👉 geogrid nrogqis pib txhav yuav deform ntau dhau ua ntej txhawb zog.
Qhov no yog vim li cas peb optimize:
Tensile modulus ntawm tsawg hom (2% -5%)
Tsis yog lub zog kawg nkaus xwb
