Xaalada guud:

Tusaale ahaan: 2M dhererka buuqa;CC 2.5M fog;Ku rakibdul duleelka.

 1.Cilmiga dabaysha xisaabi

F_wb=K_o× K₁ × K₃ × W_d × A_wh

Halkee

F_wb= Qiimaha caadiga ah ee xamuulka dabaysha (kN)

W₀= Tixraaca cadaadiska dabaysha (kN/m2)

W_d= Nakhshad cadaadiska dabaysha tixraaca (kN/m2)

A_wh=Meelaha dabayshu ka gudubto

V_5.5= Xawaaraha dabaysha saldhigga ee nakhshad ee aagga ay buundada ku taal (m/s)

V_d= Nakhshad xawaaraha dabaysha ee dhererka Z (m/s)

Z= Dhererka dhulka ka sarreeya (m)

Y=Cfnaanta cufnaanta hawada (kn/m3)

K₀= Nakhshad isku-beddelka is-beddelka ee xilliga soo noqnoqda xawaaraha dabaysha.Looxa koob ee buundada weyn ee leh hal dalool indes, k₀=1.0;buundada kale k₀=0.9;Buundada xilliga kacsiga, k₀=0.75;Marka buundada ku taal aagagga u nugul duufaanta, qiimaha K si dhexdhexaad ah ayaa loo kordhin karaa iyadoo loo eegayo xaaladda dhabta ah.

K₃= Isku-dhafka dhulka iyo xaaladaha juqraafiyeed, Guud ahaan K₃=1.0.

K₅= isku xidhka xawaaraha dabaysha, k₅=1.38 ilaa oogada A,B, ee C,D oo ah K₅=1.70.

K₂=Isbeddelka saxitaanka dhererka xawaaraha dabaysha iyadoo la tixgelinayo qaybta qallafsanaanta dusha sare iyo gradient;isku xidhka sixitaanka K₂xawaaraha dabaysha iyo dhererka kala duwanaanshaha qaab-dhismeedka hoose ee Buundooyinka ku yaal dooxooyinka intermontane, dooxooyinka ama meelaha buuraha iyo munaasabadaha kale ee gaarka ah waxaa lagu go'aamiyaa iyadoo loo eegayo qaybta dhulka ee fasalka B.

K₁= isku xidhka caabbinta dabaysha;

G= dardargelinta cufisjiidadka, g=9.8m/s2.

Qalafsanaanta dusha sare waxa loo qaybin karaa A, B,C,D.

Heerka A waxaa loola jeedaa oogada badda ee badda iyo jasiiradda, xeebta, xeebaha harooyinka iyo lamadegaanka

Fasalka B waxaa loola jeedaa beeraha, tuulooyinka, kaymaha, buuraha, magaalooyinka iyo meelaha ku hareeraysan ee leh guryo yar.

Fasalka C waxaa loola jeedaa aagagga magaalada oo leh dhismayaal cufan

Fasalka D waxaa loola jeedaa aag magaalo oo leh koox dhismayaal cufan iyo guryo sare.

Aagga waxaa iska leh fasalka C, dhererka dhulka waa 8.5m, laga helay K₀=0.9;K₁= 1.97;K₂=0.86;K₅=1.70;V_5.5=33m/s

So F_wh= k₀k₁k₃W_d A_wh= 12.63kN

2. Qiimaha naqshadeynta xoogga jiifka

S_wh=1.4Fwh=17.68(kN)

H bir mFaaska foorarsiga: M= 17.68×22.5=14.14(k·m)

Tiirka birta H wuxuu ka samaysan yahay 150x150x7x10mm bir heer qaran ah, geed la ogolyahay= 215MPa, stress xiirid 125MPah, I_x= 1660cm4, W_x=221cm3, A=40.55cm2
