Ko teADSS taura muka whatumahi i roto i te ahua o runga e tautokohia ana e nga tohu e rua me te awha nui (te nuinga o nga rau mita, neke atu ranei i te 1 kiromita), he rereke rawa atu i te kaupapa tuku iho o te "i runga" (te pou me nga waea waea paerewa mo runga i te waea whakatārewatanga kaupapa matau waea. , te toharite o te 0.4 mita he 1 kaurori).Na reira, ko nga tawhā matua o te taura muka whatu ADSS e rite ana ki nga ture o nga raina hiko hiko.
1. Whakaaetia te mahunga (MAT/MOTS)
E pa ana ki te taumahatanga i runga i te taura whatu i te wa e tatauhia ana te tapeke kawenga i raro i nga ahuatanga huarere hoahoa.I raro i tenei taumahatanga, me ≤0.05% te riaka muka me te ≤0.1% (ngongo pokapū) me te kore he whakahekenga atu.I roto i nga korero a te reimana, ka "kai" noa te taikaha roa o te muka whatu i tenei uara mana.E ai ki tenei tawhā, tikanga meteorological me te sag mana, te whanganga e whakaaetia ana o te taura whatu i raro i tenei ahuatanga ka taea te tatau.Na reira, ko te MAT he kaupapa nui mo te tatauranga o te sag-tension-span, he tohu nui ano hoki mo te tohu i nga ahuatanga o te ahotea o te taura ADSS.
2. Kua whakatauhia te kaha tensile (UTS/RTS)
E mohiotia ana ano ko te kaha tino kaha, ko te kaha pakaru ranei, e tohu ana ki te uara tatau o te tapeke o te kaha o te waahanga kawe (te nuinga o te tatau i nga muka hurihuri).Me ≥ 95% te tino pakaru o te uara tatau (ko te pakaru o tetahi waahanga o te taura ka kiia he pakaru taura).Ko tenei tawhā kaore e taea te whakakore, he maha nga uara whakahaere e pa ana ki a ia (penei i te kaha o te pourewa, nga taputapu tensile, nga mehua ohorere, me etahi atu).Mo te ahumahi taura whatu, ki te kore e tika te tauwehenga o te RTS/MAT (he rite ki te take haumaru K o te raina o runga), ahakoa he nui te muka e whakamahia ana, a he tino whaiti te awhe riaka muka whatu e waatea ana, Ko te ōwehenga mahi ohaoha/hangarau he tino rawakore.Na reira, ka tūtohu te kaituhi kia aro nga tangata o te umanga ki tenei tawhā.Ko te tikanga, he rite te MAT ki te 40% RTS.
3. Aunoa Tau (EDS)
I etahi wa ka kiia ko te ahotea toharite o ia ra, e pa ana ki te taumahatanga i runga i te taura i te wa e tatauhia ana te kawenga i raro i te hau, kaore he hukapapa me te pāmahana toharite o ia tau, ka taea te kiia ko te kaha o te kaha o te ADSS i te wa roa. mahi.Ko te EDS te tikanga (16~25)%RTS.I raro i tenei taumahatanga, kia kore he riaka o te muka me te kore he taapiri atu, ara, he tino pumau.Ko te EDS hoki te tawhā tawhito ngenge o te taura whatu, a ka whakatauhia te hoahoa anti-wiri o te taura whatu i runga i tenei tawhā.
4. Ko te raruraru whakahaere mutunga (UES).
Kei te mohiotia ano ko te awangawanga whakamahi motuhake, e pa ana ki te awangawanga i runga i te taura ka taea te neke atu i te kawenga hoahoa i te wa e ora ana te taura.Ko te tikanga ka tukuna te taura whatu ki te taumaha mo te wa poto, a ka taea e te muka whatu te tu ki te riaka i roto i te awhe iti e whakaaetia ana.Ko te tikanga, ko te UES he> 60% RTS.I raro i tenei raruraru, he <0.5% (ngongo pokapū) me te <0.35% (paparanga kua whiria) te riaka whatu whatu, a ka nui ake te whakangāwari o te muka whatu, engari i muri i te tukunga o te taumahatanga, me hoki ano te muka whatu.Ma tenei tawhā e whakarite te mahi pono o te taura ADSS i roto i tona oranga.
