Document Type and Number:
Japanese Patent JP6793505
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a survey method of a water bottom foundation capable of efficiently surveying the water bottom foundation by a surface wave survey.SOLUTION: A survey method of this water bottom foundation is the survey method of the water bottom foundation for surveying a geological structure of the water bottom foundation by receiving and measuring a surface wave generated by vibrating a water bottom by a vibration source by a plurality of receivers arrayed on the water bottom mounted on a cable at predetermined intervals. A first buoy and a second buoy are installed on a water surface on both end positions laid with the cable 20, and first and second ropes 3 and 4 and each heavy object 5 and 6 are connected one another. The cable is laid at the predetermined position of the water bottom with the heavy object as a target, and a weight 10 is dropped on the water bottom foundation surface, and the surface wave generated by the weight is received and measured by the plurality of receivers.SELECTED DRAWING: Figure 1
