摘要

大約占有75%比例山坡地的台灣本島，近幾年來，山崩的頻率似乎是有隨著地區的開發而有上昇的趨勢。發生山崩的最主要因素，是由其周遭地質環境的影響所造成。因此，本文便以本島內過去所發生過的幾件重大山崩案例作為探討的主題，希望能從山崩破壞中之各項地貌表徵、地質材料組成、地質構造延伸、水文地質條件以及地質作用等各項因子，來剖析其真正發生崩坍的機制。

Taiwan is approximately 75% mountainous. The number of landslides has been rising in recent years due to the development and new construction in the mountainous areas. The major factors causing landslides are the geological environmental reasons as they relate to the development efforts in the mountainous area. This paper chose several landslide cases for discussion. The purpose of this topic is to increase dialogue and understanding about landslide mechanisms with respect to various geomorphologic feature, geomaterial composition, structural geology, hydrogeologic conditions and geologic processes.
