中文摘要 | 921集集大地震對臺灣中部地區造成相當大的災害,本文針對臺中港區港灣設施蒐集中央氣象局地震資料及港區鑽探資料,並利用現地港區災損調查以評估災損之原因。經由調查分析顯示;台中港北碼頭區1至4A號重力式沉箱碼頭產生外移,後線水力抽砂回填區域有嚴重的下陷與大面積的凹洞,部分地區有液化噴砂及路面破裂,而北突堤第一貨櫃中心則產生不均勻的差異沉陷等災害。本文除說明港區災損情況,並分別從地震、土壤液化、碼頭設計等方向探討港灣相關設施破壞的原因,同時蒐集日本1995年阪神大地震對港灣工程所產生災害與台中港作比較分析,以期從本次地震災害學習到寶貴的經驗,提供未來港灣設施復建及填海造地耐震設計之參考。 |
英文摘要 | The 921 Chi-Chi earthquake has caused severe damages in central part of Taiwan. The main purpose of this paper is collect the related earthquake data, exploration data of harbor area, and based on the in-situ damage investigation, to evaluate the possible reasons of Taichung harbor damage caused by the 921 Chi- Chi earthquake. From the investigated results and analysis show that five wharves were seriously damaged in Taichung harbor. Displacements and tips induced by earthquake were shown in No. 1 to No. 4A wharf. Large pits and concave hole, and quayside settlement induced by sand liquefaction were found in the hydraulic reclaimed area of wharf. Parts of the roads were fractured with sand extrusion. In the north mole, non-uniform settlements were shown in the container storage area. In this paper, the damages in the harbor area are illustrated. On the other hand, the factors such as earthquake, liquefaction and harbor design are discussed to evaluate the possible reasons of the harbor damage. Comparisons are made with the Kobe earthquake in 1995, where harbor damages were caused by the earthquake. |
