台灣地區坡地災害防治工法之問題探討
The Problem Analysis of Slope Disaster Prevention Works at Taiwan
摘要
台灣山區時常發生坡地災害，特別在1999年發生了百年頻率之九二一大地震後情況尤甚，且其關鍵的觸發因子多係因爲颱風豪雨侵襲所造成。若就國內目前坡地治理工法檢討，不難發現大部分之處理工法多只就其破壞面著手，而未就其發生災害之根源所在先行探究之後再行處理，以致常於下次豪雨來臨時又再度造成坡地災害，不但造成交通中斷、影響經濟發展且增加民眾生活之痛苦指數。在坡地災害防治技術多元化之現今，若能探究災害之根源與關鍵因素並選擇最經濟有效之工程或非工程技術，當可有效提昇治理成效並節省國家財政之負擔。 一般認爲坡地開發應該要著重在；防治原則、災害防治所必需之基本資料以及坡地災害的防治技術這三大主軸，因此本研究乃以這三大主軸對仍具改善與增修空間之項目與具體改善方案之可行性進行探討。

There were many slope disasters occurred at Taiwan after 921-Gigi Earthquake in 1990. The important key of the disasters was seasonal typhoon impaction it caused traffic broken, casualties and effect human economic development. Although our government created prevention works for the landslide areas immediately, many of the control works were failure after the next year typhoon season for the reason of ignore the failure mechanism and only focused the slope surface rebuilt works. Therefore, how to be frugal the investment in created prevention works and reduced control works failed probability will become more important for government finance. There are three main shafts for slope development, such as disaster prevention principle, disaster basic characteristic and disaster prevention technique. This research under upon principle to criticism and modified the standard process of slope disaster prevention work.
