GPS/GIS/RS科技應用於高雄捷運系統大寮主機廠基礎土壤液化潛能評估分析
GPS/GIS/RS Applied on the Evaluation of Soil Liquefaction at Ta-Liau Main Depot, Kaohsiung MRT Systems in Taiwan
摘要
高雄捷運系統為南台灣重大國家交通建設之一，開闢鳳山經大寮延伸至屏東之捷運路廊，除可縮短高屏城鄉差距，與舒緩高屏公路（台1線）和鐵路之交通運輸瓶頸外，更有助益於未來大高雄都會區之區域發展，因此其興建確有其必要性。唯其行車控制中心與捷運總部所在之大寮主機廠預定地，係屬緊臨高屏溪流域之現代沖積層，其未來所面臨之基地土壤液化災害，必須納入考量，因此於大寮主機廠動工興建前，先針對該廠區及其對外連接路段，進行其沿線與廠址基礎土壤所可能發生之潛在土壤液化災害作調查研究，實屬必要。本研究以3年為期，採分年分期方式完成該路段沿線（含大寮主機廠）各項基本地工環境災害調查與相關資料蒐集，進而規劃建置鳳山至大寮路段（含大寮主機廠）潛在地層災害資料庫系統，最後應用該系統對該廠區基地土壤液化潛能進行評估，並引進GPS／GIS／RS整合技術繪製該廠區之土壤液化潛在危險區域分佈圖，以提供未來捷運施工單位作為該主機廠進入細部設計施工與其基礎土壤液化防治方案研擬之參考依據。

The Kaohsiung Mass Rapid Transit systems (K-MRT) is one of the major national construction projects in the southern Taiwan. Of which the Fengshan to Pingtung section is proposed to not only share the overloaded traffic on both county highway and railroad, but also to balance the gap of living standard between urban and rural areas and then to promote the development of Kaohsiung metropolitan surroundings ahead. The Ta-Liau Main Depot has been scheduled as an administration center and headquarters of K-MRT. Before this main depot being constructed, it is important to investigate and evaluate the potential hazards of subsurface soil deposits and rock formations.The project is to be conducted in 3 years. The purpose of this research concentrates on the fundamental geoenviroment investigations and focuses on the establishment of geohazard database along the Fengshan to Ta-Liau section, includes main depot of K-MRT. However, the soil liquefaction occurred at Ta-Liau depot would be recognized as an important issue in this study. It is expected that the established geohazard database systems, can offer an essential reference to indentify the potential soil liquefaction area for futural construction on Ta-Liau depot of K-MRT.
