Summary:The invention discloses a canal tunnel construction method for Xigeda geology, which comprises the following steps: 1) optimizing an excavation method, and controlling initial deformation; (2) advance supporting is carried out, and vertical and horizontal anti-seepage structure construction is carried out; (3) a wet spraying process is adopted, and the construction quality of sprayed concrete is controlled; (4) the lining structure is closed as soon as possible; (5) a drainage system is perfected, and stability of the arch frame and arch feet is ensured; and (6) construction of the inverted siphon pipe is completed in the tunnel. Through the research on the tunnel Xigeda stratum, a series of research results are analyzed and summarized, and the research results can be directly applied to support engineering; by changing the construction process, improving the construction environment, improving the working efficiency and saving the construction cost, the research result has very important significance on the
