建筑物沉降速率计算公式
s系数yEs可从"基础规范"表5.3.5查得`由沉降计算深度范围内压缩模量的当量值
Es = ∑Ai∑AiEsi`
i-1)a`i - zi-1a`Ai = p0(zi
式中Ai为第i层土附加应力系数沿土层厚度的积分值
∑Ai = p0 × 3.29 = 3.29p0
∑AiEsi = p0 × (3.0555.50 + 0.1159.00 + 0.1179.00 )
= p0 × (0.56 + 0.01 + 0.01)
= 0.58p0
Es = 3.29p00.58p0 = 5.66 MPa`
p0 = 86.51 kPa ≤ 0.75fak = 0.75 × 120.00 = 90.00 kPa
s = 0.8345y查"基础规范"表5.3.5得沉降计算经验系数
