崩積土의 風化度가 自然斜面의 進行性 崩壞에 미치는 影響
鄭斗永,崔吉烈,李廣俊 全北大學校 1990 論文集 Vol.32 No.-
This study is an investigation of the influence of weathering degree on progressive failure slope. The clay mineral is kaolinite in failure soil layer which distributed in Granite - Schist rock zone of the Mesozic era and the thick of it is less than 3mm in heavy weathered soils, and so the failure form is friction type. The failure layer is sandy soils which have limited influence elements in sliding movement, and so the failure type is collapse type and bed rock failure type. The relationship between Ig-loss and saturation degree is an inverse proportion in characteristics of failure soils, and the saturation degree in laboratory sliding model increase about 78% to 85% and the effective porosity is deduced in 28% to 35%. The steady pore pressure(+) which produced according to rainfall time have more effective elements under the influence of precedent rainfall or concentrating precipitation on pointed day than weathering condition of failure soils, because the heavy weathered layer and rock-cracking layer is non-development state.
