SURVEY METHOD OF WATER BOTTOM FOUNDATION
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
【課題】水底地盤を表面波探査により効率的に探査することができる水底地盤の探査方法を提供する。【解決手段】この水底地盤の探査方法は、水底を振源により起振して発生させた表面波を、ケーブルに所定間隔で取り付けて水底に並べた複数の受信器により受信し計測することで水底地盤の地質構造を探査する水底地盤の探査方法であって、第１のブイ１と第２のブイ２とをケーブル２０が敷設される両端位置上の水面に設置し、第１のブイと第２のブイとから垂下した第１および第２のロープ３．４と水底に設置された各重量体５，６とが連結されており、重量体を目標にしてケーブルを水底の所定位置に敷設し、振源として重錘１０を水底地盤面に落下させて重錘により発生させた表面波を複数の受信器で受信し計測する。【選択図】図１
