| Abstract: | The power tunnel of Tibet Road in Shanghai is the most difficult pipe-jacking project in China with long distance and large diameter. The tunnel cross through Suzhou River, underground pipelines and area of dense buildings, especially the underground passage of subway and the existing subway line 2, so it’s vital important to protect the surrounding environment when the pipe-jacking construction. Based on the construction of the tunnel, some key techniques are studied by laboratory test, numerical simulation and field measurement. The key techniques such as accuracy of pipe jacking, slurry sleeves and settlement control and their applications are described. The results indicate that the techniques can ensure the completion and achieve the demand of environmental protection. |
