In a mountain area of Kobe, a new town was to be developed adjacent to the already made new town. Construction of a deep cut-slope was required between the two towns to equalize soil amount both for cutting and banking. After about one year of slope completion, a large quantity of water suddenly burst out of the middle part of the slope. This bursting water triggered off a landslide. It was found that the accident arose from the breakdown of water pipeline linking to the pumping station which was located near the crest of the slope. Through this accident, a slipplane was formed with vertical slitting in the upper layer and flat weak plane in the lower plane, and the shear resistance of the weak plane was reduced to the residual strength. Some restraining works were given to cease any further movement of the slope. This case study may arrest attention to unexpected accidents which arise under the circumstances similar to those mentioned alove. It may also demonstrate that the influence of neighboring towns should be taken into consideration on future development of a new town.
