( 1 )板涵支架面积: 14×4=56 (m2)
( 2 )涵台台身钢筋比例换算:
HPB300 钢筋: 0.79÷ ( 0.79+0.625 ) ×1.025=0.572
HRB400 钢筋: 1.025-0.572=0.453
( 3 )支撑梁钢筋比例换算:
HPB300 钢筋: 0.086÷ ( 0.086+0.24 ) ×1.025=0.270
HRB400 钢筋: 1.025-0.270=0.755
( 4 )盖板钢筋比例换算:
HPB300 钢筋: 0.461÷ ( 0.461+2.756 ) ×1.025=0.147
HRB400 钢筋: 1.025-0.147=0.878
( 5 )混凝土拌和数量:
( 20.9+13+89+34.1+45+42.9+2.9+0.7 ) ×1.02
=253.47 (m3)
