dc.description.abstract本研究以迴轉式輸送帶渠槽帶動圓柱顆粒來進行實驗,以模擬斜坡上崩塌土體轉化為土石流之過程。 本實驗主要探討的是微觀的顆粒旋轉變形破壞現象。藉由兩種輸送帶速度(4.17cm/s、12.34cm/s)以及兩種渠槽角度(0∘、20∘)搭配成四種實驗條件來進行,利用DV拍攝實驗過程並加以分析。分析方法則是以粒子影像分析法為基礎,建立一套量測圓柱顆粒質心位移、角速度以及孔隙率之處理程式,以分析圓柱堆破壞時、破壞中及破壞後之運動機制。此外,分析底層圓柱顆粒之運動歷程,並以快速傅利葉轉換(FFT)得到其尖峰頻率。zh_TW
dc.description.abstractThis study performs experimental work with cylinders on the conveyor belt to simulate the process of landslide failure of granular particles. The experimental setup is designed to examine both the microscopic rotational deformation and macroscopic patterns. The particles image algorithm is used to study the deformation on the bottom of the assemble cylinders by shearing force. The change of porosity before and after the deformation is analyzed at different velocities (i.e. 4.17cm/s, 12.34cm/s), and slopes (i.e. 0°, 20°). We establish a method to measure the deformation, angular velocity and porosity of particles. Furthermore, we analyze the mechanism to find the peak frequency by FFT.en_US
