摘要

台灣的西南部地區之石灰岩是很好的礦產資源，主要成份爲珊瑚礁石灰岩，孔隙相當發達。因其形成至今之地質年代多尚輕、膠結不佳，極易受雨水滲透、沖刷而切割崩裂，而高雄市壽山一帶多屬此類地層，經常發生邊坡或道路坍陷情形，而釀成嚴重災害，惟相關治理案例並不多見。本文則以哨船街一帶因颱風豪雨所引起的邊坡崩塌與土石泥流災害爲例，藉由現場調查、測量與分析研判後，以自然工法施設爲原則進行邊坡崩塌整體治理及規劃，經施工完成後其邊坡穩定性已得到改善，坡面之植被也於短期內恢復，並加速自然演替現象，成功地降低邊坡崩塌的災害潛勢及景觀調和改善。

Limestone, major components are coral reefs, are very good mineral resources on southwest Taiwan area, especially at Sosan area in Kaoshiung city. There are some going badly characteristics such as more pore ration and tension crack on its surface, structure cementation not well, cause many gully, landslidel or sinking hollow and sediment disaster. This research used Sauchun street landslidel areas as experimental sites, cause by typhoon rainfall, to investigate the major reasons of landfall and estimate the combination of nature control works and traditional method planning efficacies. After slope landslide control engineering works completed, there are many vegetations growing very well and landscaped on its surface. And this area's slope stability had been successfully increased.
