本研究旨在針對花蓮銅門村土石流災害發生之原因及機制作一調査及硏究。初步之研究係先由地質、地貌及土石材料之特性先加以探討，以便作爲物理模型試驗之參考。研究方法除了現場調査、取樣外，另由航照圖之比對以了解災區地形變化及土石流觸發之特徵，並藉由土石粒徑分布之調整，進行大型直剪試驗，藉以探討材料級配對其材質特性之影響。

The purpose of this study is to investigate the cause and mechanism of the debris flow at Tungmen. This preliminary study aims mainly on the investigation of geology and topography of the site as well as the material properties. The results will be very important for model tests in the future. The methods used in this study including site investigation, sampling, photography study, and large direct shear test. Also, by testing the materials with adjusted grain size distribution, the effect on the material properties can be understood.
