3、八字 🦄 翼墙详 🐋 细计算公式

八字 🦊 翼墙计算 🌷 公式

1. 翼 🌸 墙长 🌷 度 🐎

L = H / (cot(θ) + cot(α))

L = 翼 🌺 墙 🌷 长 🪴 度

H = 路堤 ☘ 高度

θ = 坡 🌷 度 🌷 角

α = 翼 🌿 墙坡 🐵 度 🌳 角

2. 翼 🦅 墙 🕊 高度

h = H (L cot(α))

3. 翼 🐠 墙厚 🐒 度 🪴

t = W + 0.5 (h cot(α))

t = 翼墙 🌻 厚 🕷 度

W = 路肩 🦟 宽度

4. 翼墙体 🐋 积 🌷

V = 0.5 L (H h) t

5. 翼 🐧 墙坡面面积

A = (H h) (L + h cot(α))

6. 翼 💐 墙水平投 🐟 影 🐱 面积

P = L t

7. 翼墙端 🕸 部迎风面 🦍 积

A_w = 0.5 h t

8. 翼 🐴 墙端部 🐬 迎 🐶 风力

F_w = C_d ρ V_w^2 A_w

F_w = 翼 🪴 墙端部迎 💐 风力

C_d = 阻力 🐴 系数 🌼 （约为0.8）

ρ = 空气密 🦄 度

V_w = 风 🌷 速 🌸
