The invention provides a shield machine suitable for high crustal stress soft rock stratum. The machine comprises a cutter device and a shield body, the shield body is internally provided with a frontshield partition plate, the front shield partition plate is provided with an advanced tunneling passage, the advanced tunneling passage is internally provided with an advanced tunneling device, the advanced tunneling device includes an advanced tunneling cutter, a spiral blade shaft, a guide rail, advanced tunneling drive, an advanced support device and an advanced propulsion device, the advancedtunneling cutter is connected to the spiral blade shaft, the spiral blade shaft is connected to an advanced drive device, the advanced propulsion device is arranged between the advanced drive deviceand the advanced support device, the advanced support device is supported on the shield body, and the guide rail is arranged at the advanced tunneling passage. The machine has the advantages that themachine not only facilitates the early release of the energy accumulated in a rock body, but also utilizes an expansion and contraction function of the shield body to achieve secondary stress release,and achieves integrated construction of horseshoe-shaped full-section excavation, slag discharge and lining machinery of the high crustal stress soft rock stratum.
