正确答案
H1=(76.86+76.46+76.37+76.88/4)=76.74m
H2=(76.46+76.04+76.88+76.41/4)=76.45m
H3=(76.37+76.75+76.88+76.32/4)=76.58m H
4=(76.88+76.41+76.32+76.81/4)=76.61
H0=H1+H2+H3+H44=76.57m
各点挖填方高差依次为:+0.29,+0.31,+0.24,+0.18,-0.10,-0.53,-0.20,-0.16,-0.25。
设每一方格的面积为400m2
VA1=0.29×1/4×400=+29;VB1=-0.2×2/4×400=-40
VA2=-0.10×2/4×400=-2;VB2=+0.31×400=+142
VA3=-0.53×1/4×400=-53;VB3=-0.16×2/4×400=-32
VC1=+0.18×1/4×400=+18 VC2=-0.25×2/4×400=-50
VC3=0.24×1/4×400=+24
V挖=195m2;V填=195m3
自然地平面平均高程为76.57m,填挖方体积为195m3。
