Introduction Concrete is wildly used in building engineering for its good durability, plasticity and low price [1-5].
We use about one billion stere of concrete every year [6], however, the service life of concrete engineering reduced because of the cycle loading and damage accumulation.

As a regional metamorphic rock, the engineering properties of the phyllite are rather complex [4-5]. so it is significant to study the stress variation rules of initial support stress and secondary lining of phyllite tunnel in the construction process.
