Abstract

In order to study the cost of the steel reinforcement construction in the subway station, through the analysis of the correlation between the costs of labour and ancillary equipment on the process of subway station construction, and the analysis of the correlation between the cost and the duration, and then established mathematical model of the correlation between the costs of labour and ancillary equipment and the correlation between the cost and the duration, which were based on the statistical analysis. So that it has been on the positive direction of controlling the cost and the duration on the subway construction. By the theory of coupling coordination degree model, explored the coupling mechanism of the costs of labour and ancillary equipment, and the coupling mechanism of the cost and the duration, at last established coupling mathematical model based on the data of statistical analysis. Those statistical data included No. 1 and No. 12 section of the Changsha Metro 3rd Line, and No. 6 and No. 7 section of the Changsha Metro 4th Line. Model results showed that the standard coordination degree of coupling coefficients in No. 1 and No. 12 section of the Changsha Metro the 3rd Line, and No. 6 , No. 7 and No. 8 section of the Changsha Metro the 4th Line. By calculating the value of the degree of coordination were 0.9852, 0.9414, 0.9668, 0.6515 and 0.5383. Besides, the result of analytical computation showed that the duration decreased with the increase of the coefficient of the coordination degree. When the proportion of the cost of labour and ancillary equipment was 1, the total cost was minimum. Besides, when the proportion of the cost of labour and ancillary equipment was 1, the duration was the shortest time. So when on the process of subway station construction, we should adjust to the best value of the proportion between the cost of labour and ancillary equipment.
