桥梁下构工程量计算

1:桥梁桩基础计算:

号桩基:(1.82)2(66-52)4=142.430m3

..④号桩基计算如上

⑤号桩基:左幅:(1.82)2(69-55)2=71.215m3

右幅:(1.82)2(71-55)2=81.389m3

2:桥墩计算:

号墩:(1.52)2(77.429-66)4=80.746m3

好墩:(1.52)2(77.328-66)4=80.032m3

号墩:(1.52)2(77.219-66)4=79.262m3

④号墩:(1.52)2(77.102-66)4=78.436m3

⑤号墩:左幅:(1.52)2(76.99-69)2=28.225m3

右幅:(1.52)2(76.982-71)2=21.131m3

⑥号墩:左幅:(1.52)2(76.978-57.5)2=68.806m3

右幅:(1.52)2(76.973-57.5)2=68.788m3

3:系梁计算:

D为37.5px时由系梁与桥墩的结构关系得

求角度:sinx=6075=0.8则x=5307,

扇形面积:nr23600=(5307,23.140.752)3600=0.52m2

三角形面积:(1.20.45)2=0.27m2

小半圆面积:0.52-0.27=0.25m2

两个小扇形面积:(0.31.2)-0.25=0.11m2

一个系梁的工程量为:(61.2+0.112)1.4=10.388m3

全桥D为37.5px的系梁工程量:10.38810=103.88m3

D为45px时

求角度:sinx=6090=0.667则x=41048,

扇形面积:(41048,23.140.92)3600=0.59m2

三角形面积:[1.2()]2=0.40m2

小半圆面积:0.59-0.40=0.19m2

两个小扇形面积:1.2[0.9-()]-0.19=0.35m2

一个系梁的工程量为:[(7.5-1.8)1.2+0.352]1.4=10.556m3

全桥D为45px的系梁工程量:10.55610=105.56m3

⑥号桥台:(1.5+1.6)13.9920.5=43.369m3

13.9921.5(1.7-0.5)=50.364m3

0.7540.52=3m3

[(1.98-1.2)+4]2.750.5=6.573m3

{[(0.25+0.375)0.5]2}1.24=0.75m3

43.369+50.364+3+6.573+0.75=104.056m3

0号桥台:

基础:

[9.9(30.7+3.351)1+9.2(20.7+3.251)1+9.939(30.7+3.351)1+9.939(2o.7+3.351)1]2=398.1m3

挡块:[(0.375+0.25)0.5]21.14=0.6875m3

垫石:0.1321[(0.36-0.125)2]=0.444m3

台身:(9.94+0.7)24.652=197.9m3

(13.99-1.5)26.52=324.74m3

(197.9+324.74)25.55=725.16m3

13.992825.552=1242.31m3

1242.31-725.16=517.15m3
