河床下地質構造の把握に対する表面波探査の適用性 APPLICABILITY OF SURFACE WAVE METHOD TO GEOLOGICAL PROFILE UNDER RIVERBED 川尻, 峻三 KAWAJIRI, Shunzo 渡邊, 康玄 Watanabe, Yasuharu 森田, 大詩 MORITA, Taishi 新妻, 重明 NIITSUMA, Shigeaki 木下, 誠一 KINOSHITA, Seiichi Surface wave method S-warn velocity N-vale geological profile under riverbed This paper is considering the applicability of the surface wave method for understanding the geological profile under the riverbed. The profile of S-wave velocity and the N-value were well matched. Therefore, S-wave velocity in the grom1d of the river zone can be treated as an indicator similar to the N -value. It is reasonable estimate of the geological cross-sectional view by using the S-wave velocity distribution. In addition, the pseudo-three-dimensional dist1ibution of S-wave velocity, was consistent with the local situation. As a results, the use of the S-wave velocity distribution obtained from the surface wave method, it is possible to create the 3D hazard map for riverbed degradation and improving the accuracy of the analysis model. journal article 土木学会 2016-06 application/pdf 河川技術論文集 22 55 60 https://kitami-it.repo.nii.ac.jp/record/2000014/files/kasengijutu_22,55-60.pdf https://kitami-it.repo.nii.ac.jp/records/2000014 jpn c 2016 土木学会 open access
