碩士 === 國立屏東科技大學 === 水土保持系 === 93 === This research was taken in hillside community the Xin-Ba-Ke village at Taichung Da-Keng, which undertakes all the related slope monitoring facilities establishment and regular observations. Proceeding analysis from the data that was collected there. To understand the possible disaster that caused by the earthquake in the Xin-Ba-Ke village. This research institute concludes the results as followed: 1.Extrapolating the subsoil water level situation during the torrential rain or the rainstorm period, the relation between the rainfall amount of each month and subsoil water level of each month, which may apply on obtaining the subsoil water level relations of the important critical time. 2.In the stratum variation situation aspect, each dipmeterT1~T4 and the T13~T14 on the corresponding retaining columns to the "No.2 Incline Meter" and "No.4 Incline Meter", all showed distinct changes. This demonstrates the stratum is livelier, which must continue the observation. 3.The heights peep out such as 4.5, 5.5, 6.5, and 7.5 meters coordinate to extrapolating groundwater level. After calculating the depth of penetrating safety coefficient from the simulation under the condition of retaining columns before and after the full water level test, that concludes the current situation on retaining columns the depth of penetration is obviously insufficient and insecured. 4.Disregard the effects of the pile foundations under the buildings base, the slope stability analysis of those 3 regions considered to be more dangerous, was found that the blanket of soil in the area might having a flat surface glide.
