2004年10月，第23号台风袭击日本西部。对大面积的基础设施造成严重破坏。10月21日清晨，兵库县矢部市山区发生了最大高度约23 m的大型Terr Armee墙的破坏。加固后的堤坝上的泥石流附着在脚下的一个仓库上，但没有人员伤亡的报告。事件发生后，当局随即成立一个委员会，负责调查这次灾难性斜坡倒塌的原因，并研究该区是否可能再发生斜坡灾难。在本文中，边坡破坏的机制与可能的原因进行了讨论的基础上进行的稳定性分析，利用实验室和现场数据，再加上拓扑信息和降雨数据。结合多雨山区修建陆军墙的实践，介绍了该案例的一些教训。
In October 2004, Typhoon No. 23 attached western part of Japan. causing severe damage to infrastructures over a wide area. In the early morning on 21 of October, a failure of large Terr Armee wall with the maximum height of about 23 m took place in mountainous area in Yabu city, Hyogo Prefecture. The flow debris from the reinforced embankment attached a warehouse on the foot, however, no casualties were reported. Immediately after the incident, a committee was set up with missions to investigate the cause of this catastrophic failure and also to examine any possible occurrence of further slope disasters in this region. In this paper, the mechanism with possible causes of the slope failure was discussed based on the results of stability analysis performed using laboratory and field data, coupled with topological information and the rainfall data. Some lessons learnt from this case record are described with reference to the construction of Terr Armee wall in rainy mountainous area.
