2011年东北太平洋沿岸地震导致房屋和住宅区严重受损。特别是，仙台市中心周围的住宅用希尔赛德设施遭受严重破坏。许多在1978年宫城县地震中受损的希尔赛德地受到进一步的破坏。本文对仙台市典型的山坡地进行了调查，并对山坡地破坏的原因进行了探讨。房屋破坏的主要原因不是地震运动，而是填土路堤的地面位移。比较2011年地震和1978年地震的破坏情况，可以看出1978年地震后采取的对策在防止大规模滑坡型破坏方面效果良好，但在减少因裂缝、不均匀沉降和浅层滑动引起的地面位移对房屋或住宅用地造成的破坏方面并不成功。提出了填土路堤破坏类型的分类方法，为选择防治措施提供了依据。
The 2011 off the Pacific Coast of Tohoku Earthquake resulted in severe damage to housing and housing lots. In particular, the hillside embankments for residential use surrounding the downtown of Sendai city suffered serious damage. Many hillside lands which had been damaged during the 1978 off Miyagi-Prefecture earthquake were subjected to further damage. Typical damaged hillside embankments in Sendai city were investigated and the causes of the damage were discussed in this paper. The main cause of the damage to housing was not the seismic motion but the ground displacement of the fill embankment. A comparison of the damage from the 2011 earthquake with that from the 1978 earthquake indicates that the countermeasures constructed after the 1978 earthquake performed well in that they prevented large landslide type failure; however, they were not successful in reducing the amount of damage to housing or housing lots due to ground displacements from cracks, differential settlement, and shallow slips. A classification of failure types of fill embankment is proposed to be of assistance in the choice of countermeasures.
