The invention discloses tunnel high-strength sprayed concrete. The tunnel high-strength sprayed concrete comprises, by mass, 450-480 parts of concrete, 800-820 parts of coarse aggregate, 900-920 partsof fine aggregate, 4-5 parts of a water reducing agent and 160-180 parts of water. The concrete has the cement consumption of 450-480 kg/m, the cement to aggregate ratio of 1:(4-3.5) and the sand ratio of 45-55%, the water cement ratio is controlled to be 0.3-0.4 during spraying, an accelerator is mixed in the concrete, and the mixing amount of the accelerator does not exceed 4% of the weight ofthe cement. Thus, the tunnel high-strength sprayed concrete meets the requirements for the strength of concrete construction in a business line and other physical performance, is low in strength lossafter construction, and can guarantee the operation safety of the business line.
