摘要

崩塌地治理首重邊坡破壞誘因之瞭解與破壞機制之調查，本文是以位於嘉義縣大埔鄉曾文水庫保護帶之泰山地層滑動災害為例進行調查分析。得知該地區由於長期受到雨水逕流漫流與入滲之影響，加上劇烈的沖蝕溝切割淘刷作用，致使邊坡逐漸失去支撐平衡而發生地層之滑移。幸經緊急修築地表排水與蝕溝控制工程整治後，邊坡因而趨於穩定，惟局部地區因開路不當而仍有沉陷坍滑的可能，應隨時進行必要的維護管理工作。

It was the most important to realize the temptation factor and to investigate the mechanism of slope failure before the prevention works planning. Then, there were very good efficacy depended on the data and parameter of investigation result for undertaking the suitable prevention works planning. This planning site, Tai-Shan Landslide in Tseng-Wen Reservoir Watershed, was unstable and giving rise to landslide disaster as a result of the influences of runoff overflow and rainfall infiltration and erosion of gully cutting. The slope stability increased by way of prevention works construction, but part of the slope was induced sliding again owing to the unsuitable road build. Thus, maintenance and management would become more important afterward on landslide area.
