| Abstract: | Taking Shanghai Beiheng Channel and Zhoujiazui Road Tunnel as the background,this paper studies the seam waterproofing of large-diameter,high-hydraulic pressure and sharp-curve shield tunnel through the engineering analogy,numerical simulation,waterproofing performance test and structural construction.The study result shows that the elastic sealing gasket can resist the hydraulic pressure of 12 MPa when the seam is 6 mm open and 10 mm staggered.And it is applied in the above project,and its implementation effect is good. |
