(1)Load factor
Zvinoenderana nedhizaini yebhiriji remugwagwa uye dhizaini yekuvaka yakapihwa neBazi rezvekutakurwa, iyo coefficient yekutakura ndeyekutevera:
Iyo yakawandisa coefficient yekuwedzera maitiro uye zvimwe zvinhu kana bhokisi girder kongiri inodururwa: 1.05;
Dynamic coefficient yekudira kongiri :1.2
Impact factor yeFomu Mufambi Kufamba pasina mutoro:1.3;
Kugadzikana coefficient yekupokana nekupidigura pakudurura kongiri uye Fomu Mufambi: 2.0;
Chengetedzo yekushandiswa kwakajairika kweFomu Mufambi ndeye 1.2.
(2)Rodha pane truss huru yeFomu Mufambi
Iyo Bhokisi girder mutoro: Bhokisi girder mutoro kutora yakakura kwazvo kuverenga, huremu i411.3 matani.
Zvishandiso zvekuvaka uye mutoro wevanhu vakawanda: 2.5kPa;
Mutoro unokonzerwa nokuraswa uye kuzunguzika kwekongiri:4kpa;
(3)Rodha musanganiswa
Mutoro musanganiswa wekuoma uye kusimba kwekutarisa :Concrete huremu+Fomu Mufambi uremu+chishandiso chekuvaka+mhomho yeruzhinji +vibration simba kana tswanda ichifamba: huremu hweFomu Mufambi+kuremerwa kwemufambi (0.3*huremu hweFomu Mufambi)+the mhepo mutoro
Tarisa kune tekinoroji yekumisikidza yekuvakwa kwemigwagwa mikuru mabhiriji uye ma culverts zviga:
(1) Huremu hwekutonga kweFomu Mufambi uri pakati pe0.3 ne0.5 nguva dzekongiri kurema kwekongiri yekudira.
(2) Yakanyanya kubvumidzwa deformation (kusanganisira huwandu hwechipfuramabwe deformation): 20mm
(3) Chengetedzo chinhu chekudzivirira kupidigura panguva yekuvaka kana kufamba: 2.5
(4) Chengetedzo chinhu cheself anchored system:2
