大規模地震災害緊急運送之規劃-以大臺北地區為例

Planning of Emergency Transportation for Massive Earthquake Disasters–Case Study of the Taipei Metropolitan

指導教授 : 施邦築

摘要


大台北地區為我國最大的都會區,在臺北市、新北市二個行政區即近六百六十萬人口數,屬高人口密集地,並擁有完善交通路網系統。據經濟部地調所2010年版活動斷層圖調查,此地區內擁有一條山腳斷層,位於大臺北地區的關渡至新莊,台北盆地和林口台地間,為臺北盆地之西緣,長約11公里,北北東-南南西走向延伸至東北外海,屬第二類活動斷層,其致災之潛在威脅實不可輕忽。如大台北地區未來面臨此山腳斷層錯動所引致大規模地震,導致整個道路交通系統部份損毀,引起疏散指揮之混亂現象,無法確實發揮救援、疏散的機能。   本研究以山腳斷層錯動所導致之大規模地震,利用臺灣地震損失評估系統(TELES)進行震災境況模擬,參考過去相關案例之專家學者的建議,將模擬地震的芮氏規模訂為6.9,震央位於經度121.589度、緯度25.139度,斷層破裂長度、寬度分別為56公里、20公里,震源深度取8公里,斷層傾角平均為50度。因此,本研究將以下重要課題,研擬因應對策模擬此震災境況,評估包括:(1)道路橋梁損毀之緊急應變及復原; (2)大眾運輸道路損毀之應變作為;(3)防救災道路規劃;(4)災區廢棄物之清運。綜合上述模擬課題,建立一套救災公路系統,使其於災前有效整合各單位之搶救災資源,並於災害發生時協助產生緊急搶救的應變措施,規劃替代道路,維持災後之交通運輸機能,使災後的復原重建工作能順利推展,期使災損與衝擊降至最低,將為現階段防救災工作的重要課題。

The greater Taipei area is the biggest metropolis in Taipei. In Taipei City and New Taipei City, these 2 administrative districts have a population around 6.6 million, where can be considered as a high dense populace and have a well-developed transportation road network system. However, based on the active fault map survey 2010 version that made by the Central Geological Survey (CGS), Ministry of Economic Affairs (MOEA), this area has a Shanchiao fault where located at the middle between the Guandu to Xinzhuang in the greater Taipei area; between Taipei Basin and Linkou Tableland at the west edge of Taipei Basin, its length is about 11 km, NNE –SSW trending and stretching to the northeast outer-sea, which is a Type 2 active fault, and its potential threat to cause disasters really shouldn’t be neglected. For example, in case of large-scale earthquake that caused by the faulting of Shanchiao fault in the greater Taipei area, that may result in partial damage to the entire transportation road system and consequently cause a chaotic evacuation; therefore, it is not able to certainly display its function of rescue and evacuation.   This study used the large-scale earthquake that caused by the faulting of Shanchiao fault as the object and utilized Taiwan Earthquake Loss Estimation System (TELES) to carry out the Seismic Scenario Simulation. By referring to experts’ and scholars’ suggestions from previous related cases, it set Richter magnitude scale to be 6.9 for this Earthquake Simulation, and its epicenter to be located at Longitude: 121.589 and Latitude: 25.139; length and width of fault rupture are 56 km and 20 km respectively; 8 km for the depth of focus; and dip angles of fault are average 50 degrees. As a result, this study investigated and developed these countermeasures for certain seismic scenario simulation according to the following tasks, and those consequent assessments included: (1) Emergency response and restoration of damaged roads and bridges; (2) Countermeasures of damaged public transportation; (3) Route planning of disaster prevention and rescue; and (4) Waste cleaning and moving for disaster area. In addition, this study integrated these aforesaid simulative issues to establish a disaster rescue highway system which could be effectively integrated with the resources of disaster rescue from individual emergency unit before disaster occurred, and, in case of disasters, assisted them to yield the countermeasures of emergent rescue, plan alternative routes and maintain transportation function after disaster in order to make smooth restoration work after disasters occurred; therefore, it hoped to minimize the loss and impact that caused by disasters and that would be the most important issue for disaster prevention and rescue at the moment.
