| Abstract: | With the construction of a 26-km super-large sewer trunk in Shanghai as a practical example,a technically and economically comparative study and analysis are made of two trenchless construction methods for the construction of the 26-km super-large sewer trunk in the paper：jacking and sheilding.It is found that the two construction methods are both fairly mature technically.However,the jacking construction scheme is found to have the advantage of being good in integrity,high in security,and lower in cost,which is 17.1% lower than that of the shield construction scheme in the integrated unit price. |
