| In Japan，many types of deep mixing methods were proposed for cost reduction. However，in case of the high embankment and rapidly construction，it is a serious problem to stop to the lateral flow and compression failure of cement columns，bearing failure of soft gruund. Therefore，to makes possible the high embankment and rapidly construction，we propose the new deep mixing method which inserts steel into the cement improvement area under the embankment slope and ties steel with anchor cable. We conducted centrifuge model experiment to confirm the effectiveness of new method and to select suitable spec. As conclusion, we knew that the new proposal method is effective for high embankment and rapidly construction and most effectiveness parameters are the pitch of steel and the length of steel. |
