0206美濃地震高鐵電車線設備搶修作業 The HSR Emergency Repair Operations of the February 6th Meinong Earthquake
懸臂組搶修作業。

105年2月6日小年夜凌晨3時57分高雄美濃發生芮氏規模6.4、深度16.7公里的淺層強震,導致高鐵左營站至彰化站北端,約計156.5公里路線發生地震告警,台南市歸仁區震度甚至高達398gal(接近芮氏規模7級震度),造成高鐵台南段及嘉義段東/西正線多處電車線系統(OCS)線形與結構嚴重受損、張力平衡裝置導桿變形、配重塊破裂/位移、架空地線絕緣礙子破裂、懸臂斷裂、拉桿臂斷裂/扭曲變形及吊線/掛線折損變形/斷裂/脫落等,嚴重影響高鐵營運。高鐵公司遂取消6日全日台中站至左營站區間之營運,並即刻召回全台所有OCS維修人員(104人,含支援廠商12人),調集嘉義至左營區間內所有OCS維修工程車全力投入搶修,以期儘速完成路線開通,紓解春節前搭車人潮。維修人員不分日夜全力搶修後,於7日早上6時50分完成台南段搶修及全線OCS送電作業,維修人員始獲片刻喘息。
7日營運前,巡軌車巡檢時發現嘉義段經前日下午4時起以每小時兩班列車方式行駛台中至嘉義區間,誘發未明顯外露瑕疵產生劣化或破壞之多處新災損。高鐵公司遂再召集所有維修人員,先以長梯投入嘉義段搶修,並佐以OCS維修工程車進行搶修及受影響區域之巡檢,以避免遺漏其他潛在未顯露的瑕疵。再經過12小時的搶修作業,遂於2月7日下午6時恢復全線正常營運。
地震發生後,胡局長湘麟率本局同仁連續兩天陪同交通部陳部長建宇至高鐵台中車站督導疏運作業,2月7日另赴嘉義段督導電車線搶修作業。本局同仁於年假期間亦持續聯繫高鐵公司維修值勤人員,以即時掌握系統損壞情形及搶修進度,並要求高鐵公司持續改進天然災害的檢視及搶修作業程序,以落實監理作業。

On Feb. 6th, 2016 at 3:57 am, just before Chinese New year, a Richter scale 6.4, depth 16.7 kilometers shallow earthquake happened in Meinong District, Kaohsiung City causing earthquake alarm from HSR Zuoying Station to north of Changhua Station to ring, effecting approximately 156.5 kilometers of HSR route. In Guiren District, Tainan County, the seismic intensity even reached 398gal (equal to Richter scale 7), resulting in severe damage in HSR Tainan and Chiayi sections. Damages to the system included alignment and structural damage in multiple OCS systems of the East / West main line, distortion of the rod of tension-balancing devices, rupture and displacement of balance weight blocks, rupture of the overhead ground wire insulators, fracture of cantilevers, fracture and distortion of lever arms, deformation, fracture and falling of wires and droppers, etc. so greatly impacted HSR operation. In consequence, THSRC cancelled all operation between the interval of Taichung Station and Zuoying Station on Feb. 6th and addition to instantly recalling all domestic OCS maintenance staff (a total of 104 people including 12 from supporting vendors), THSRC also mobilized all OCS maintenance vehicles within the area of Chiayi to Zuoying to put full power into repairing the damages in order to re-open the HSR line and relieve the crowd of Chinese New Year holidays. After going through 24 hours around the clock of full repairing operations and bearing dramatic temperature changes of day and night, the maintenance team completed repairing Tainan section and full power transmission of OCS operations at 6:50 in the morning of Feb. 7th and could finally catch a breath.
Before re-opening operation on Feb. 7th, the rail patrol car discovered multiple new deteriorated and broken damages in Chiayi section that were not significantly exposed possibly induced by the operation of two trains per hour between Taichung and Chiayi starting from 4pm the day before. Subsequently, THSRC instructed all maintenance crew to prioritize repairing Chiayi section with long ladders and utilize the OCS maintenance vehicles to repair and patrol other affected area in order to avoid missing potential flaws that were not revealed. With another 12 hours of repairing operation, the HSR system restored full range of normal operation at 6pm on Feb. 7th.
Instantly after the happening of the earthquake, BOHSR Director General Hu led associates to accompany Minister Chen of MOTC two days in a row to HSR Taichung Station to inspect the passenger dispersing situation. Then on Feb. 7th, the inspection party traveled to the Chiayi section to inspect on repair work of the OCS system. During the holidays, associates of BOHSR has continued to contact THSRC on-duty maintenance personnel to grasp updated system damage and repairing information. In addition, BOHSR requested THSRC to continuously improve inspection and repairing operations procedures for natural disasters in order to carry out actual supervision work.
