The present paper proposes an evaluation method for pipeline damages by using average S wave velocity and liquefaction potential decided by S wave velocity in each layer ( an evaluation method of liquefaction potential was proposed in 1990 ) determined by Surface wave exploration. Average S wave velocity and liquefaction potential between ground surfa-ce boundary of liquefaction layer are calculated. Average S wave velocity iscalculated to use Root Mean Square (R.M.S.) equation. Liquefaction potential is decided by area enclosed with Vs■Vscr which was proposed in 1990. It is evaluated that liquefaction potential is low in case of small area and high in case of large one. Evaluation of a drainpipe damage was carried out in Shohnan area in Noshiro city, Akita prefecture where was attacked by Nihonkai Chuubu Earthquake (1983.5.26,M=7.7). It was found that average S wave velocity was low and area was large in damaged area but average S wave velocity was high and area was small in non-damaged area. This method isuseful for evaluation of lifeline damages in the area where may be attacked by a big earthquake in the near future. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
