◉Ngasekupheleni kwephrojekthi yokubeka imigqa, ukuvikelwa kocingo nekhebula kanye nezindlela zokuzikhethela zokumisa sekuphenduke amaphrojekthi amaningi okuqeda inkinga, futhiithreyi lekhebulanjengoba ukuqedwa kwalo msebenzi kuwukuphela kwenketho.
◉Kodwa-ke, kunezitayela eziningi zethreyi yekhebula, indlela yokukhetha kahle nangempumeleloithreyi lekhebulanezesekeli empeleni kuyinto yokufunda. Ezimweni eziningi, uhlangothi lobunjiniyela bomugqa olunikezwe uhlelo lokwakha, olubonisa ukuhlelwa kwengxenye ngayinye yomugqa. Okuqukethe okuqukethwe komugqa ngenombolo evamile, usayizi wamandla (noma ububanzi bekhebula), inani lama-shunts, isiqondiso sokufinyelela nokunye. Le datha ngokuvamile okungezona ochwepheshe kunzima ukuyiqonda, ukuze ukwazi ukukhetha ithreyi yekhebula ngokusebenzisa imidwebo yokwakhiwa komugqa futhi kudingeka uhlaziye idatha etholwe kulokhu okuqukethwe kokubala. Inqubo ethize imi kanje:
◉1, khetha okufaneleithreyi lekhebula.
Ngokuhambisana nenani lokufinyelela engxenyeni ngayinye ye-node namandla okubala ububanzi bekhebula ngalinye, elihlelwe ngokuhambisana nezikhathi ezi-3 ububanzi bezikhala zekhebula, okuholela ebubanzini bethreyi yekhebula. Bese ubala indawo ye-cross-sectional yethreyi yekhebula ngokuya nge-70 ~ 85% yendawo yokupholisa, ihlukaniswe ngendawo enqamulayo yobubanzi bethreyi yekhebula ukuze ufike ekuphakameni kwethreyi yekhebula. Uma indawo yesakhiwo sethreyi yekhebula ethintwa isikhala ayikwazi ukuba phezulu, noma ingakwazi ukuba banzi. Ithreyi yekhebula enezimbotshana ingasetshenziswa ukwandisa ukusebenza kahle kokukhipha ukushisa, ingancishiswa ibe ngu-35 ~ 50% wesikhala esidingekayo ukuze kukhishwe ukushisa. Ngaphezu kwalokho, ingasetshenziswa futhi ukuxazulula inkinga ngokungafaki ipuleti lekhava.
◉2, bala ubude bomugqa.
Okokuqala, ngokuhambisana nemidwebo ebhalwe ukuthi ama-circuit nodes ukubala ubude bendlela, bonke ubude bobude obuphelele obubalwe ngokuhambisana nendlela eyodwa kubude obuphelele bama-nodes axhunywe ezingxenyeni zebanga elihlobene. Bese imidwebo ibhalwe ngamunye ngamunye. Ngakho, ngokobude bengxenye ngayinye yobude ihlukaniswe ngobude beyodwaithreyi lekhebulaukuthola inombolo yezimpande, inani lemisila libe munye. Ngaleyo ndlela ukuqinisekisa zonke izikhundla ezidingekayo zemodeli yethreyi lekhebula kanye nenani.
◉3, khetha isixhumi esifanele.
Ingxenye ngayinye yosayizi wethreyi lekhebula iqinisekisiwe, indawo yenodi ngokuya ngokuma okuqondile nokuvundlile kwelungiselelo lendawo enyakazayo yethreyi yekhebula. Kukhona ingxenye ye-intersecting noma egoqayo yamajoyinti adinga ukukhethwa ukuze enze ngokweqile, ngaphezu kobukhulu bosayizi wethreyi yekhebula yamajoyinti futhi kudingeka kwandiswe amalunga anciphisa. Izinketho eziqondile zimi kanje: Okokuqala, ukuphambana kwendawo lapho umzila wendlela yezindlela eziningi zokukhetha inani lamalunga, isibonelo, umzila uphambana phakathi nendawo ekugcineni kwenye indlela, engabonwa. iyindlela engu-3, ngakho-ke ukukhetha kwe-tee, ububanzi bamathreyi ekhebula ezinkomba ezintathu buhambisana nobubanzi bamalunga e-tee. Khona-ke, ngokuqondisa okuvundlile ekhoneni, kufanele kusetshenziswe indololwane evundlile, ikakhulukazi i-90 °, futhi amakhona aqondile adinga ukukhomba ukuqondanisa ngaphandle noma ngaphakathi kwendawo yokugoba, khetha ithreyi yekhebula ngaphandle kokugoba noma ngaphakathi. isixhumi sokugoba. Ekugcineni, ekugcineni ukuqondanisa angakhetha ukuvala ipulaki yethreyi yekhebula.
◉4, khetha ukufanisa inani lezixhumi nezisekelo.
Ithreyi yekhebula ngokuyinhloko incike ekuxhumekeni kwesiqephu soxhumano, imininingwane evamile yohlobo lwethreyi yekhebula ekugcineni kwezingcezu ezimbili zezingcezu zokuxhuma. Ngemva kokubala inani eliphelele lamathreyi ekhebula, phindaphinda inani lenombolo ngo-2 ukuze ubale inani lezixhumi ezidingekayo zethreyi yekhebula. Ukufakwa kwe-Tee kanye ne-4-way kubalwa ngokuphindaphinda inombolo yezindlela ngo-2 ukuze kubalwe inani lezicucu zokuxhuma. Izindololwane nezinciphisi zibalwa ngokuphindaphinda inani eliphelele lamathebhu ngamabili.
Inani lezintambo eziphansi lilingana nenani lamathebhu oxhumano. Inombolo yezibophelelo zokuxhuma ibalwa ngokuphindaphinda inombolo yamathebhu okuxhumana ngo-6.
Inani lamasethi amabakaki ethreyi yekhebula libalwa ngokuphindaphinda isamba senani lamathreyi ekhebula kanye nenani eliphelele lezindololwane ngo-2. Amakhona akhethekile noma izindawo zokugxumeka kufanele ziboniswe emidwebeni eyengeziwe.
◉ Izinyathelo ezine ezingenhla zizodingeka kuphrojekthi inombolo yethreyi yekhebula kanye nezinsiza ezibaliwe, bese ekuthengeni kwe-oda kufanele kwandiswe cishe ngo-5% wezingxenye ezisele. Inombolo yomkhiqizo owodwa ingaphansi kwezingcezu ezingu-20 okungenani zezingxenye eziyisipele ezengeziwe ukuze kuqinisekiswe ukuthi iphrojekthi ayinangqondo.
→ Kuyo yonke imikhiqizo, izinsizakalo kanye nolwazi lwakamuva, sicelaXhumana nathi.
