- Cov yam ntxwv ntawm kev ua tau zoo
- Lub Zog Siab: Nws muaj lub zog tensile siab thiab tiv taus kev rhuav. Nws tuaj yeem tswj tau lub zog zoo thiab cov yam ntxwv elongation txawm tias nyob rau hauv lub xeev qhuav lossis ntub. Nws tuaj yeem tiv taus lub zog tensile loj thiab cov zog sab nraud thiab tuaj yeem txhim kho lub zog tensile ntawm cov av thiab txhim kho kev ruaj khov ntawm cov qauv engineering.
- Kev Ruaj Khov Zoo: Nws muaj kev ua tau zoo tiv thaiv kev laus thiab tuaj yeem tiv taus kev cuam tshuam ntawm cov yam sab nraud xws li ultraviolet hluav taws xob, kev hloov pauv kub, thiab kev yaig tshuaj lom neeg ntev. Nws tuaj yeem siv tau ntev hauv cov xwm txheej sab nraum zoov hnyav. Tib lub sijhawm, nws muaj kev tiv thaiv zoo rau kev xeb tshuaj xws li kua qaub thiab alkali thiab tsim nyog rau ntau qhov chaw av thiab dej nrog cov nqi pH sib txawv.
- Kev Nkag Tau Dej Zoo: Muaj qee qhov sib txawv ntawm cov fibers, uas ua rau nws muaj dej zoo - permeability. Nws tsis tsuas yog tso cai rau dej hla mus zoo tab sis kuj tseem cuam tshuam cov av me me, xuab zeb zoo, thiab lwm yam, kom tiv thaiv kev yaig av. Nws tuaj yeem tsim cov kav dej hauv av kom ntws cov kua thiab roj ntau dhau thiab tswj kev ruaj khov ntawm dej - av engineering.
- Muaj zog tiv thaiv kab mob me me: Nws muaj kev tiv thaiv zoo rau cov kab mob me me, kev puas tsuaj ntawm kab, thiab lwm yam, tsis yooj yim puas tsuaj, thiab tuaj yeem tswj tau kev ua haujlwm ruaj khov hauv cov av sib txawv.
- Kev Tsim Kho Yooj Yim: Nws yog lub teeb thiab mos hauv cov khoom siv, yooj yim rau kev txiav, nqa, thiab tso. Nws tsis yooj yim rau deform thaum lub sijhawm tsim kho, muaj kev ua haujlwm zoo, thiab tuaj yeem txhim kho kev ua haujlwm ntawm kev tsim kho thiab txo qhov nyuaj thiab tus nqi ntawm kev tsim kho.
- Cov Ntawv Thov
- Kev Tsim Kho Txoj Kev: Nws yog siv rau kev txhawb nqa ntawm cov qib hauv qab ntawm txoj kev loj thiab kev tsheb ciav hlau. Nws tuaj yeem txhim kho lub peev xwm ntawm cov qib hauv qab, txo cov kab nrib pleb thiab kev hloov pauv ntawm txoj kev, thiab txhim kho kev ruaj khov thiab kev siv tau ntev. Nws kuj tseem siv tau rau kev tiv thaiv txoj kev nqes hav kom tiv thaiv kev yaig av thiab kev nqes hav.
- Kev Tsim Kho Kev Txuag Dej: Hauv cov qauv hydraulic xws li pas dej, cov qhov dej ntws, thiab cov kwj dej, nws ua lub luag haujlwm ntawm kev tiv thaiv, tiv thaiv kev ntws, thiab kev ntws dej. Piv txwv li, ua cov khoom siv tiv thaiv rau cov pas dej kom tiv thaiv kev yaig dej; siv rau hauv kev tsim kho tiv thaiv kev ntws, ua ke nrog geomembrane los tsim cov qauv tiv thaiv kev ntws kom tiv thaiv dej ntws zoo.
- Kev Tsim Kho Kev Tiv Thaiv Ib Puag Ncig: Hauv cov chaw pov tseg, nws tuaj yeem siv rau kev tiv thaiv - seepage thiab kev cais tawm kom tiv thaiv cov av pov tseg los ntawm kev ua qias tuaj rau hauv av thiab dej hauv av; nws kuj tseem siv tau rau kev kho cov pas dej tailings kom tiv thaiv kev poob ntawm cov xuab zeb tailings thiab kev ua qias tuaj rau ib puag ncig.
- Kev Tsim Kho Vaj Tse: Nws yog siv rau kev kho kom ruaj khov ntawm lub hauv paus tsev kom txhim kho lub peev xwm thiab kev ruaj khov ntawm lub hauv paus; hauv cov haujlwm tiv thaiv dej xws li hauv qab nthab thiab ru tsev, nws yog siv ua ke nrog lwm cov ntaub ntawv tiv thaiv dej kom txhim kho cov nyhuv tiv thaiv dej.
- Lwm Cov Teb: Nws kuj tseem siv tau rau kev tsim kho vaj tse, xws li kho cov hauv paus ntoo thiab tiv thaiv kev yaig av; nyob rau ntawm ntug dej hiav txwval tidal flats thiab reclamation projects, nws ua lub luag haujlwm ntawm kev tiv thaiv kev yaig thiab kev txhawb nqa av nplaum.
