Ni mu buhe buryo igipimo cy'amasoko ($ k $) kibarwa ku mpinduka nyinshi Crest-to-Crest isoko y'amazi, kandi ni ibihe bintu bitera kutagira umurongo uko wegera uburebure bukomeye?

Igipimo cyamasoko $ k $ kumpinduka nyinshi Crest-to-Crest umuraba wamazi ufite shim amaherezo akomoka kuri formula: $ k = \ frac {E \ cdot b \ cdot t ^ 3 \ cdot N ^ 4} kuri buri cyiciro, $ D_m $ ni cyo kigereranyo cya diameter, na $ Z $ ni umubare wibikorwa bifatika. Mu myitozo, umutwaro-gutandukana umurongo ukomeza kuba umurongo hagati ya 20% na 80% ya deflection iboneka. Mugihe amasoko yegereje 'uburebure bukomeye', imiraba itangira 'gutega' cyangwa gukoraho, bigabanya neza uburebure bwibikorwa byigiti kandi byongera umubare wumuraba $ N $ ukora muburyo bubangikanye. Ibi bitera kwiyongera cyane mubipimo byimpeshyi, bikunze kugaragazwa nka $ k_ {nyabyo} = k_ {theoretical} \ cdot (1 - \ frac {f} {h}) ^ {- 1} $ aho $ f $ ari gutandukana na $ h $ ni uburebure bwubusa, nubwo hakenewe ibizamini bifatika kugirango habeho kwerekana neza uburebure bwimbitse.
