Geosynthetic Rau Kev Txhim Kho Hauv av
Geosynthetics tau hloov kho kev txhim kho hauv av los ntawm kev muab tus nqi- siv tau zoo, ruaj khov rau lwm txoj hauv kev xws li kev khawb loj lossis tshuaj lom neeg ruaj khov. Es tsis txhob hloov cov av "phem", peb siv cov ntaub ntawv no los txhim kho nws cov khoom uas twb muaj lawm.
Lub luag haujlwm tseem ceeb hauv kev txhim kho hauv av
Kev txhawb zog:Ntxiv tensile lub zog rau av (uas yog zoo ntawm compression tab sis txaus ntshai ntawm nro).
Kev sib cais:Tiv thaiv cov av mos subgrade los ntawm kev sib xyaw nrog qib siab -cov txheej txheem zoo.
Lim/Drainage:Tso dej kom dhau mus thaum khaws cov av hauv qhov chaw, tiv thaiv "piping" lossis yaig.
Containment:Xauv cov av nyob rau hauv qhov chaw kom tsis txhob kis mus rau sab nraud.

Yam tseem ceeb ntawm Geosynthetics
| Hom | Thawj Siv Case | Nws ua haujlwm li cas |
| Geogrids | Pavements, tuav phab ntsa, qhov chaw siab tshaj. | Siab - nruj mesh uas "interlocks" nrog aggregate los tsim lub platform nruj. |
| Geotextiles | Txoj kev, dej txheej, embankments. | Woven lossis non{0}}woven fabrics siv rau kev sib cais thiab pom. |
| Geocells | Kev tswj kev yaig, kev txhawb nqa hnyav. | Lub 3D honeycomb qauv uas txwv cov av / pob zeb, tiv thaiv nws los ntawm kev txav mus los ntawm qhov hnyav. |
| Geocomposites | Retaining phab ntsa, landfills. | Ib tug hybrid (piv txwv li, ib tug tub ntxhais rau ntws nrog ib tug ntaub rau pom) los daws complex dej teeb meem. |
| PVDs | Mos av nplaum consolidation. | "Wick drains" uas ua rau kom tshem tawm cov dej los ntawm cov av saturated kom tiv thaiv kom ntev - nyob. |
Cov ntawv thov siv
Saj zawg zog Pavement Stabilization
Los ntawm tso ibgeogridlos yogsiab - zog geotextilenyob rau hauv lub interface ntawm subgrade thiab lub hauv paus chav kawm, koj muaj peev xwm txo qhov yuav tsum tau thickness ntawm koj gravel. Nws faib lub log load hla ib cheeb tsam dav, uas tiv thaiv rutting.
Mos Av Consolidation
Yog tias koj tab tom tsim "muck" lossis cov av nplaum mos, tsim cov qauv hnyav yuav ua rau lub xyoo ntawm lub dab dej. Los ntawm kev txhim khoPrefabricated Vertical Drains (PVDs)thiab siv cov av ib ntus "surcharge," koj tuaj yeem nyem cov dej tawm thiab ua tiav 90% ntawm kev sib hais hauv lub hlis ntau dua li kaum xyoo.
Reinforced Av Slopes (RSS)
Es tsis txhob tsim cov phab ntsa kim pob zeb, koj tuaj yeem siv cov khaubncaws sab nraud povtsegthawj geogridmus "wrap" av. Qhov no tso cai rau koj los tsim ntau qhov chaw siab tshaj (txog 70-90 degrees) uas yog cov nroj tsuag thiab av qeeg- tiv taus.
Kev xav txog engineering
Kev xaiv tsis yog hais txog lub zog xwb; koj yuav tsum saib:
Aperture Loj:Rau geogrids, lub qhov yuav tsum tau qhov loj me kom raug rau qhov tshwj xeeb pob zeb / gravel siv.
Creep:Ntau npaum li cas cov khoom yuav ncav cuag 50-75 xyoo nyob rau hauv tas li load.
Environmental Degradation:Kev tiv thaiv UV teeb thaum lub sij hawm installation thiab av pH theem ib zaug faus.
Pro- lus qhia:Rau kev txhim kho hauv av, "Kev Sib Tham Coefficient" yog txhua yam. Nws yog ib qho kev ntsuas ntawm qhov zoo ntawm cov av "grips" geosynthetic. Yog tias lawv tsis sib raug zoo, cov khoom siv tsuas yog ib daim ntawv nplaum hauv av.
