Abstract

Li X.-Z.; Zhu, Y.-Q., and Zhao, J., 2019. Seepage analysis and optimization of engineering method for municipal underwater tunnel construction in urban coastal stratum. In: Gong, D.; Zhu, H., and Liu, R. (eds.), Selected Topics in Coastal Research: Engineering, Industry, Economy, and Sustainable Development. Journal of Coastal Research, Special Issue No. 94, pp. 260–263. Coconut Creek (Florida), ISSN 0749-0208.

A municipal tunnel is a double-deck tunnel shared by traffic and municipal corridors. It is an underwater tunnel in the coastal stratum. Water seepage must be considered during the tunnel construction process. By establishing a three-dimensional geo-mechanical calculation model and considering the seepage, the construction process of the two construction methods, the step method and the CRD method, is analyzed. The CRD method is better in controlling tunnel deformation, tunnel seepage and pore water pressure distribution.
