Nrog kev nce ntawm PVA cov ntsiab lus hauv geotextile, lub zog qhuav thiab ntub lub zog ntawm cov khoom sib xyaw geotextile tau zoo heev.Lub zog qhuav / ntub dej ntawm cov ntshiab polypropylene geotextile yog 17.2 thiab 13.5kN / m feem.Kev cuam tshuam ntawm luv fiber ntau cov ntsiab lus ntawm 400g / m2 geotextile ntawm qhuav thiab ntub lub xeev
Thaum PVA cov ntsiab lus yog 60%, qhov qhuav / ntub tawg lub zog ntawm geotextile yog mus txog 29 7, 34.8kN / m . Ntawm ib sab, lub siab modulus thiab lub zog siab polyvinyl cawv muaj lub zog siab thiab tsis yooj yim rau kev tawg raws li kev ua ntawm sab nraud quab yuam, thiab acupuncture tov nrog PP staple fiber tuaj yeem ua lub luag haujlwm ntxiv dag zog;Ntawm qhov tod tes, linear ceev ntawm polypropylene staple fiber ntau hauv geotextile yog 6.7 dtex, thaum linear ceev ntawm high modulus thiab siab zog PVA yog 2.2 dtex.
Kev cuam tshuam ntawm luv fiber ntau cov ntsiab lus ntawm 400g / m2 geotextile ntawm qhuav thiab ntub lub xeev
Nyob rau hauv geotextile, muaj ib tug loj tus naj npawb ntawm siab modulus thiab siab zog polyvinyl cawv fibers, uas nws linear ceev yog me me, uas ua rau lawv nruj nreem intertwined, yog li txhim kho cov mechanical zog ntawm geotextile.
