碩士 === 國立中興大學 === 水土保持學類 === 84 === This research includes the investigation of the engineering properties on the compacted slope filled materials and landsliding monitoring work at HOMSI golf field, Taiping, Taichung county, Taiwan. Emphases are placed on : (1) the experimental study of soil properties under different grain size distribution and compact effort. (2) land sliding stability was analysed based on the monitored data of sliding surface. The research results are summarized as follows: (1) With the maximum grain size fixed at No.#10 mesh and compact effort below 237.08 KJ/M^3,the less the small grain size distribution of the test object is, the larger its maximum dry density is. When compact effort is above 474.16 KJ/M^3,its maximum dry density is determined by the grain size distribution and plasticity index. (2) Under the condition of the same water content and compact effort, the cohesion force increases as small size distribution and compact effort increases. While the friction angle increases as compact effort increases, and decreases as small grain size distribution decreases. (3) The preliminary dry density ,cohesion force ,and friction angle of the compact soil were estimated by water content, compact effort, and grain size distribution. (4) The strength of the compact soil is definitely weakened when the soil column was soaked. The water content affect the slope stablity greatly.
