碩士 === 國立中興大學 === 水土保持學系 === 87 === Nan Tou situats at central of Taiwan . Because it has many mountains , high density of erosion and geology is brittle , So hillside fields often occur erosion by harmful drainage caused area of 7 ha . By theoretical analyses , investigation , laboratory and field tests , the result were summarized as follow : （一） Many factors involved in landslide , it includes weak topography , soil erosion and bad surface drainage , That give rise lower region to collapse and cause landslide . （二） Composited of geological structure and strain’s value and a analysis of landslide depth . It can shows hillside slope stability analysis . If it can strengthen surface drainage and dredge erosion tunnel , calamity does not occur easily . （三） Many regions have slope stability except toe of landslide is still change . So it must plan prevent treatment and still proceed periodical observation . （四） Analysis of hydrological information , we have forecast equation as follow : qi=(2*R*0.24)/(1.0013+3.0011) R： volume of rainfall per day qi：volume of groundwater
