Theknoloji e tsoetseng pele ea borokho ba Single box girder

Beam ea lebokose la tšepe, eo hape e bitsoang steel box girder, ke mokhoa o tloaelehileng o sebelisoang bakeng sa marokho a malelele. Ka kakaretso e sebelisoa ka marokho a maholo a marang-rang, e bitsoa tšepe ea lebokose la litšepe hobane e shebahala joaloka lebokose.E ka aroloa ka mefuta e meraro: borokho bo nang le lebokose le le leng la borokho, borokho ba marako a mabeli, le borokho ba multiple girder .
Ka har'a marokho a tšehelitsoeng ka lithapo tse kholo tse nang le lithapo tse kholo, thipa e kholo ea lebokose la tšepe e pharalla ka limithara tse makholo a 'maloa kapa esita le limithara tse likete.
E arotsoe ka likarolo tse 'maloa tsa maballo bakeng sa tlhahiso le ho kenya,' me karolo ea eona ea sefapano e na le litšobotsi tsa sebopeho se pharaletseng le se bataletseng, 'me karolo ea likarolo e fihla hoo e ka bang 1:10. Steel box girder ka kakaretso e entsoe ka ho chesella ka botlalo poleiti e kaholimo, poleiti e ka tlase, webo, le likarolo tse pharalletseng, li-partitions tsa longitudinal le li-stiffeners. Letlapa le ka holimo ke mokato oa borokho oa orthotropic o entsoeng ka sekoaelo le li-longitudinal stiffeners. Botenya ba poleiti e 'ngoe le e' ngoe ea girder e tloaelehileng ea lebokose e ka ba: botenya ba sekoahelo 14mm, longitudinal likhopo tse bōpehileng joaloka 6mm, bophara ba molomo o ka holimo 320mm, bophara ba molomo o ka tlaase ke 170mm, bolelele ba 260mm, sebaka sa 620mm; botenya ba poleiti e ka tlase ke 10mm, li-stiffeners tsa longitudinal tse bōpehileng joaloka U; Botenya ba tepo e sekametseng ke 14mm, botenya ba tepo e bohareng ke 9mm; sebaka sa li-partitions tse pota-potileng ke 4.0m, 'me botenya ke 12mm; bophahamo ba seretse ke 2 ~ 3.5m.
