Nws yog cov tswv cuab ntawm tsev neeg loj ntawm cov khoom siv geosynthetic thiab siv dav hauv txoj kev loj, kev tsheb nqaj hlau, kev txuag dej, kev tsim kho kom loj, - nplai kev tsim kho, kev tsim hluav taws xob tsob ntoo tshauv ua kev tsim kho, tsis yog - ferrous hlau tailings kho, ib puag ncig kev tiv thaiv engineering, dej thiab av kev txuag, thiab lwm yam.
Qhov teeb meem ntawm kev pab cuam lub neej ntawm cov kev sib xyaw geomembrane feem ntau yog txiav txim siab los ntawm seb zaj duab xis yas poob nws cov anti - seepage thiab dej - thaiv cov nyhuv. Raws li cov kev cai ntawm Soviet Union lub teb chaws tus qauv, a 0 .2 - meter - tuab polyethylene zaj duab xis nrog stabilizer siv nyob rau hauv hydraulic engineering nyob hauv cov dej huv lub sijhawm ua haujlwm tuaj yeem ncav cuag 40 ~ 50 xyoo, thiab lub sijhawm ua haujlwm hauv cov dej qias neeg yog 30 ~ 40 xyoo. Yog li no, kev pab cuam lub neej ntawm cov pawg geomembrane yog txaus kom tau raws li kev pab cuam lub neej ntawm kev tiv thaiv kev tiv thaiv ntawm kev tiv thaiv - seepage.
Cov khoom lag luam: ib daim ntaub nrog ib zaj duab xis, ob daim ntaub nrog ib zaj duab xis, ntau daim ntaub nrog ntau cov yeeb yaj kiab, thiab lwm yam.
Cov yam ntxwv khoom: kev sib xyaw anti - seepage thiab ntws dej, siab zog, txhuam cov coefficient loj, tiv thaiv kev tiv thaiv kev laus, kev tiv thaiv kev laus, kua qaub thiab alkali tsis kam, thiab tiv thaiv av av.
