摘要： PROBLEM TO BE SOLVED: To easily find a crack in the ground by forming a bore hole in the ground, laying the bore hole in water flowing state, measuring the underwater potential distribution laid along the bore hole, and determining the position having a specific distribution. SOLUTION: In the ground to detect the presence of a crack 3, a bore hole 1 is formed, and water is carried into the bore hole 1. When the water permeable crack 3 is present in the middle of the bore hole 1, the tomographic state around it is changed to change the potential distribution of water, and this position is detected as the crack 3. In order to eliminate the influence of potential distribution by a difference in geological structure, the water flow in the bore hole is stopped to measure the potential distribution of stationary water. The potential distributions in water flowing and stationary states are mutually compared, whereby the crack 3 can be more precisely detected from the specific potential distribution caused in water flowing time. To measure the potential distribution, a reference electrode 21 is stopped within the bore hole 1, a probe electrode 22 is moved along the inside of the bore hole 1, and the potential in each position within the bore hole 1 is measured by a voltmeter 24.

摘要： PROBLEM TO BE SOLVED: To perform a precise measurement by arranging a plurality of electrodes on the ground, measuring the potential difference between the electrodes, and probing the ground from the potential difference between the electrodes. SOLUTION: A plurality of electrodes 10 are mounted on the ground around a tunnel, a lead wire 20 is delivered from each electrode 10, and the potential of each electrode 10 is measured by a voltage measuring equipment 21. The ground generally has a flow of water such as groundwater, and when the water is carried to a water channel 30, a potential difference is produced in the peripheral ground by electrokinetic phenomenon. The electrodes 10 in the ground measure the potential difference, and when a fluctuation such as crack is caused in the ground to change the flow of water, the potential distribution in the peripheral ground is changed. Consequently, the electrodes 10 detect the fluctuation of voltage, whereby the fluctuation of the ground can be known.

摘要： PURPOSE: To increase the safety of cutting faces, by constructing a plurality of reinforcing walls longitudinally and restricting the deformation of the cutting face of a tunnel by the top support of the reinforcing wall and the contact resistance between the respective reinforcing walls and the ground and excavating the cutting face and the reinforcing walls. CONSTITUTION: A longitudinal reinforcing wall 20a is constructed along the excavating direction from the cutting face 10 of a tunnel, prior to the excavation of the cutting face of tunnel. In this case, the reinforcing wall 20a serves as supports to bear the upper part and the ground positioned between reinforcing walls 20a comes into contact with the reinforcing walls and prevents the deformation to the axial direction of the tunnel in the ground due to the frictional resistance between both material. Next, the reinforcing walls 20a together with the whole section of the cutting face 10 of the tunnel are excavated as the objectives and the shield 30 of tunnel is also extended at the same time. Subsequently, the same reinforcing walls with respective reinforcing walls 20a left in the cutting faces are constructed adjacently thereto. The reinforcing walls newly constructed support the cutting face in stead of the reinforcing walls 20a and stabilize it. In this way, excavation, shield, and construction of reinforcing walls are repeated to extend the tunnel.
