Vim li cas Geogrid Performance Parameters yog qhov tseem ceeb
Hauv geotechnical engineering, qhov ua tau zoo ntawm geogrid nyob ncaj qha rau nws cov khoom siv kho tshuab thiab lub cev. Kev ntsuam xyuas kom raug ntawm cov kev ntsuas no yuav pab tau:
- Txhim kho kev muaj peev xwm ntawm cov av tsis muaj zog
- Txo qhov sib txawv ntawm qhov sib txawv thiab deformation
- Txhim kho load hloov efficiency
- Extend kev pab cuam lub neej ntawm infrastructure
- Txo cov nqi tsim kho thiab kho kom tsawg
Ua tsis tiave los txiav txim siab txog cov kev txwv no yuav ua rau muaj kev tsis ruaj khov lossis ua tsis tiav ntxov.
Kev soj ntsuam ntxaws ntxaws ntawm Key Geogrid Performance Parameters
Tensile zog yog qhov tseem ceeb tshaj plaws parameter ntawm geogrids. Nws txhais tau tias qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej tsis ua haujlwm.
Cov txiaj ntsig zoo sib txawv los ntawm:
25 kN / m txog 110 kN / m (los yog siab dua nyob ntawm cov khoom qib)
Lub zog tensile siab dua yuav tsum muaj nyob rau hauv hnyav - daim ntawv thov xws li txoj kev loj, tshav dav hlau, thiab khaws cov qauv.
Geogrids yog tsim nrogtsis tshua muaj elongation yam ntxwv, xyuas kom tsawg deformation nyob rau hauv load.
- Tsawg elongation txhim kho av confinement
- Txo cov sij hawm ntev - kev sib hais haum
- Txhim khu kev ruaj ntseg
Creep resistance yog qhov tseem ceeb sib npaug, tshwj xeeb tshaj yog rau cov ntawv thov ntev - lub sijhawm uas siv cov loads tas li.
Junction zog hais txog lub zog ntawm kev sib tshuam ntawm cov tav.
- Xyuas kom muaj kev thauj mus los zoo
- Ua kom muaj kev ntseeg ruaj khov
- Tiv thaiv kab sib chaws tsis ua hauj lwm hauv kev ntxhov siab
High junction lub zog yog qhov tseem ceeb rau kev tswj xyuas tag nrho cov kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov av txhawb zog.
Qhov loj aperture txiav txim siab npaum li cas aggregate particles cuam tshuam nrog geogrid.
- Qhov loj me me aperture txhim kho kev sib tshuam ntawm kev sib tshuam
- Txhim khu kev sib txhuam ntawm cov av thiab kab sib chaws
- Ua kom tag nrho cov kev siv zog ntxiv
Qhov kev ntsuas no yuav tsum raug xaiv raws li hom khoom siv siv, xws li pob zeb lossis pob zeb crushed.
Cov cuab yeej txhawb nqa ntawm geogrids tso siab rau ntaumechanical interlocking thiab kev sib txhuam.
- High interlock txhim kho load faib

- Moisture thiab kub variations
High- zoo geogrids yog tsim nrog stabilizers thiab additives los xyuas kom meej ntev - lub sij hawm durability, feem ntau tshaj kaum xyoo ntawm kev pab cuam lub neej.
Hom geogrid yob dav dav li ntawm4 rau 6m, uas muaj ntau yam zoo:
Kev txhim kho sai dua
Txo kev sib tshooj
Cov nqi zog qis dua
Txhim kho kev tsim kho efficiency
Engineering Design thiab Installation Considerations
Kev txhim kho kom zoo yog qhov tseem ceeb los xyuas kom meej tias geogrids ua tau raws li tsim.
Lub hauv paus yuav tsum tau leveled thiab compacted los muab kev txhawb nqa zoo ib yam.
Lub ntsiab tensile kev taw qhia yuav tsum ua raws li tus thawj coj kev ntxhov siab.
Hauv ntau- cov ntawv thov txheej, kev sib tshooj thiab kev sib raug zoo yog qhov tsim nyog los tswj kev txuas ntxiv.
Kev siv dej kom zoo yog qhov tseem ceeb los tiv thaiv cov dej hauv av, uas tuaj yeem txo cov av muaj zog.
Siv geotextiles rau kev pom
Nruab cov kav dej lossis cov kav dej
Tsis txhob txhaws kom muaj kev ua haujlwm ntev -
Kev xaiv cov khoom siv thiab qhov project optimization
Thaum xaiv geogrid, cov hauv qab no yuav tsum tau xav txog:
Cov av tsis muaj zog los yog mos yuav tsum muaj zog tensile ntau dua thiab kev ua haujlwm zoo dua.
Hnyav tsheb los yog siab loads xav kom muaj zog geogrids nrog tsawg deformation yam ntxwv.
Txoj kev tsim kho → Biaxial geogrid
