The invention provides a TBM tunnel ventilation system and a TBM tunnel. The ventilation system comprises an air supply pipe, an air draft device, an air supply device, an air exhaust transverse channel and an air supply transverse channel. The TBM tunnel comprises a first tunnel body and a second tunnel body, the air supply pipe is arranged in the first tunnel body and the second tunnel body, one air outlet of the air supply pipe supplies air to the tunnel face of the first tunnel body, the other air outlet of the air supply pipe supplies air to the tunnel face of the second tunnel body, and the air supply device is arranged in one of the first tunnel body and the second tunnel body and is close to the corresponding tunnel face. The air supply device communicates with the air inlet so as to supply air to the two tunnel faces. The first tunnel and the second tunnel are communicated through the exhaust transverse channel, and the air draft device is arranged in the exhaust transverse channel to extract dirty a
