Double-layer steel-concrete combined lining shield tunnel suitable for crossing geological fault and construction method of double-layer steel-concrete combined lining shield tunnel

The invention discloses a double-layer steel-concrete combined lining shield tunnel suitable for crossing a geological fault and a construction method of the double-layer steel-concrete combined lining shield tunnel. The double-layer steel-concrete combined lining shield tunnel suitable for crossing the geological fault comprises a lining tunnel body; a lining structure arranged in the lining tunnel body, wherein a spacing cavity is formed between the lining structure and the lining tunnel body; and a damping structure arranged in the spacing cavity. The lining structure comprises a lining steel pipe and a concrete structure; at least part of the pipe wall of the lining steel pipe is of a hollow structure; and the hollow structure is filled with the concrete structure. The lining structure formed by combining the lining steel pipe and the concrete structure is arranged in the lining tunnel body, and the damping structure is arranged in the spacing cavity, so that under the condition that the driving space of
