Abstract：The test result of in-situ stress in Jinchuan diggings demonstrates that the area is of higher in-situ stresses. The destruction model and stability of the tunnel largely depend on the quantity and direction of in-situ stress. As the excavation depth and in-situ stress increase，the manipulation of the field stress in the excavation area becomes harder. Thus，the disclosure of the in-situ stress law is important for optimum control technology and tunnel supporting design. The test material of in-situ stress in the diggings is collected，and the prediction model of in-situ stress is developed，based on neural network theory. The main conclusion is achieved after the prediction and analysis of in-situ stress in the digging.
