Immersed tunnel suitable for cross-geological fault and construction process thereof

The invention discloses an immersed tunnel suitable for a cross-geological fault and a construction process thereof. The immersed tunnel suitable for the cross-geological fault comprises a tunnel body, a seismic isolation cushion layer, limiting structures and energy consumption structures, wherein the tunnel body comprises a plurality of immersed tube sections which are sequentially connected, and each immersed tube section comprises a top plate, a bottom plate and a web plate; the seismic isolation cushion layer is arranged below the tunnel body; the limiting structures are arranged at the joints of the adjacent immersed tube sections, and the limiting structures are arranged in the vertical direction; and the energy consumption structures are arranged on the top plates, the bottom plates and the web plates respectively, and the energy consumption structures are arranged in the axial direction of the tunnel body. According to the immersed tunnel suitable for the cross-geological fault, the seismic isolation
