Abstract：
Squeezing deformation is an urgent problem to be solved in the construction of soft rock tunnel in the ar?
ea with high ground stress, and deformation prediction is the key to controlling tunnel deformation under high ground stress. On the basis of previous research results, the grade and magnitude of large squeezing deformation of certain soft rock tunnel are predicted by squeezing factor method and peripheral strain method respectively, pertinence control measures are proposed, the predicted results agree with the measured values, providing a reference for the construction of similar projects.
