this paper makes multiple measurements during the construction process of tunnel’s portal section
including convergence deformations of surrounding rocks
stresses of bolts
stresses and deformations of primary and secondary liners
which give a great number of testing data. On this basis
numerical analysis is performed
the results provide reliable and scientific basis for both design and construction salty of the liners. Not only can all this work guide constructing technique of the tunnel under consideration but also accumulate valuable referential data for the projects of the same kind.
