博士 === 逢甲大學 === 土木工程所 === 98 === The CO2 evaluation and examination of the public infrastructure is still in the initial stage. This study aimed to calculate the quantity of materials required for each unit with different span lengths and widths according to the designs of the prestressed type I bridge, and conduct a regression and curve analysis through SPSS statistics to calculate the equation of CO2 emission volume. Further, the relation between the CO2 emission volume and the bridge width and span length estimated by this research was divided into the following 7 categories: seismic zone A soil Ⅰ: CO2(kg-CO2/unit)=1051.318+0.937(span length)-13.8(bridge width) seismic zone A soil Ⅱ: CO2(kg-CO2/unit)=1257.3+1.475(span length)-17.18(bridge width) seismic zone A soil Ⅲ: CO2(kg-CO2/unit)=1171.681+1.324(span length)-15.987(bridge width) Taipei basia area: CO2(kg-CO2/unit)=1163.166+0.986(span length)-14.818(bridge width) seismic zone B soil Ⅰ: CO2(kg-CO2/unit)=1014.852+1.216(span length)-12.919(bridge width) seismic zone B soil Ⅱ: CO2(kg-CO2/unit)=1168.321+2.214(span length)-14.902(bridge width) seismic zone B soil Ⅲ: CO2(kg-CO2/unit)=1141.793+1.219(span length)-15.113(bridge width) There was no significant difference among the estimated coefficients of the emission volume equation under different design conditions. Indeed, the mean volume was taken for the regression and curve analysis. The estimated equation is shown below: Average CO2 emission volume: CO2(kg-CO2/unit)=1138.347+1.339(span length)-14.96(bridge width)
