By this financial support, the first objective of this research is successfully achieved as follows ; The failure mechanism of slope surface subjected to rainfall, is expressed by three stages model, 1. Descent of wetting front, 2. Appearance of under-ground water, and 3. Failure of slope surface layer.The second objective was to clarify the effect of plants covering the slope. However, it cannot be completed, because the time is not sufficient, though the effects of plant are to change the seepage characteristic and to reinforce the surface soil layer.The slope soils are not so homogeneous as alluvial soils. Then, how to determine the soil parameters is the other important problem. In this research some field test methods including new ones were used. Although some conditions of field test to determine the parameters were suggested, development of practical methods will be one of the future themes.

通过这笔资金支持，本研究的第一个目标成功实现如下；降雨作用下坡面破坏机理可以用三阶段模型来表示：1。2.湿润锋下降；2 .地下水的外观；坡面层破坏。第二个目标是阐明植物覆盖斜坡的效果。虽然植物的作用是改变渗流特性，加固表层土层，但由于时间不够，无法完成。斜坡土不像冲积土那样均匀。然后，如何确定土壤参数是另一个重要问题。本研究采用了包括新方法在内的几种现场试验方法。虽然提出了一些确定参数的现场试验条件，但开发实用的方法将是未来的主题之一。
