To improve construction efficiency by concretely recognizing characteristics of the natural ground in front of a shield machine and reflecting them to construction conditions of a tunnel construction.
When setting boring conditions of a shield machine, boring by the shield machine is stopped in step S1. Sampling of sediment of the natural ground in front of the shield machine is performed by using a sediment sampling device in step S2. Properties (particle size distribution characteristics or water permeable characteristics) of the sampled sediment and a division thereof are determined in step S3. Setting of the boring conditions of the shield machine is performed on the basis of the properties and the division of the sediment determined in step S4 in step S4. Concretely, kind, property, and injection ratio of a mud-added material injected into a cutter chamber when boring by the shield machine, an earth pressure in the cutter chamber when boring by the shield machine, and a boring advancing speed of the shield machine are set as the boring conditions.
