摘要：

The levee or natural slope of a waterway can be influenced by ship wave during a vessel operation and it is examined how the wave height can affect the slope stability analysis in this study. The result for two rock slopes indicates that the safety factors for planar and wedge failures are reduced by 19.6 similar to 20.3% and 12.0 similar to 21.3%, respectively. In case of two soil slopes, they are reduced by 5.8% and 8.5%. This interpretation considering a ship wave reflects the actual field condition better, which there exist some of rock falls and soil erosions. Therefore, wave height needs to be used as groundwater level at the slope stability analysis considering continuous ship wave effect. Slope stability analysis along the waterway should also be done by reflecting wave pressure, slope saturation condition, and freezing and thawing action judging from the slope phenomenon.
