高鐵鐵路「地震後橋梁緊急搶修演練」觀摩 Observation for HSR “Post-earthquake Bridge Emergency Repair Exercise”

台灣高鐵公司為因應強烈地震可能對沿線土建設施及橋梁結構造成危害預做因應,於11月16日特別在台南新化路段,舉辦國內首次「地震後橋梁緊急搶修」大型演練。本局楊副局長率相關同仁出席觀摩,對台灣高鐵展現應變力、確保旅客安全、降低營運衝擊精進作為,致辭肯定及期許。台灣高鐵公司江耀宗董事長指出,台灣位處環太平洋地震帶,地震發生機率頻繁,雖然高鐵系統在設計興建之初即已充分考量土建設施的耐震度,符合國家規範標準。但為防範超過耐震設計之強震之發生可能,高鐵公司特別率業界之先舉辦「地震後橋梁緊急搶修演練」,不僅強化員工教育訓練,更希望參考國外經驗,並透過實做演練與工程界及軌道同業相互切磋交流。一旦不幸遭遇巨變,台灣高鐵將可迅速利用國內、外資源,立即展現最大動員及復舊能力,盡快恢復營運,減少對旅客造成的影響,提供民眾安全、便捷的旅運服務。
本次演練,預設情境為台南新化地區發生強烈地震,震後巡檢發現:橋梁支承、胸牆及伸縮縫蓋板等設施受損。其中,高鐵里程TK299+264橋墩底部混凝土遭破壞、鋼筋挫屈、塑鉸發生,產生垂直向及橫向的位移,盤式支承等裝置受損。演練項目包括:整地及鋪設臨時基礎、架設支撐架及千斤頂、拆除連結裝置、大梁復歸原位、移除橋墩塑鉸、橋墩復歸原位、橋墩修復及補強等項目。透過電腦模擬、縮時攝影以及人員解說等方式,完整呈現「地震後橋梁搶修」之全貌。
為達成本次演練項目,高鐵公司動員協力廠商出動35噸拖板車達100車次,出動大型挖土機、吊卡車、移動式吊車及水準儀等大型機具投入,歷時4個月籌備。演練運用之「型鋼重型支撐架」及「H型鋼」多達465公噸、水泥及預拌混泥土達200立方公尺;參觀單位尚包括臺鐵局、鐵改局、公路總局以及台南市政府、台灣世曦工程顧問公司等單位均派員觀摩,見證國內首度舉辦之「地震後橋梁緊急搶修」大型演練。

In response to the possible occurrence of a strong earthquake that may cause damage to the civil works and bridge structures along the HSR route, THSRC held its first large-scale “Post-earthquake Bridge Emergency Repair Exercise” on Nov. 16, especially at the Xinhua section of Tainan. BOHSR Deputy Director General Yang led associates to attend the event to observe. The Deputy Director General showed approval toward the resilience of the THSRC to ensure passenger safety and reduce operational impact. THSRC Chairman Y. C. Chiang indicated that Taiwan is located in the Pacific Rim so the frequent occurrence of earthquakes is predictable. Although the HSR system has fully taken into account the seismic strength of civil facilities at the beginning of design and construction and is in line with the national norms and standards, THSRC is the first to host the “Post-earthquake Bridge Emergency Repair Exercise” in order to prevent the occurrence of strong earthquakes that exceed the seismic design potential. It not only strengthens employees' education and training but also hopes to make reference to foreign experience and practice through hands-on training to exchange views with engineering and rail counterparts. In the event of a catastrophic, THSRC will rapidly utilize domestic and foreign resources to immediately demonstrate maximum mobilization and resilience and resume operations as soon as possible to reduce the impact on passengers, providing people with safe and convenient travel services.
In this exercise, the scenario was set for a strong earthquake at Xinhua, Tainan as follows.
"After the quake, the inspection revealed that the facilities such as bearings, parapets and expansion joints of the bridge were damaged. Among them, the bottom of concrete pier at HSR mileage TK299 + 264 was damaged, steel was buckled, plastic hinges occurred, resulting in vertical and horizontal displacement. Also, the pot bearing and other devices were damaged. The matters addressed in the exercise include: site preparation and laying of temporary foundation, erection of support frames and jacks, removal of linkage devices, return of girders to their original locations, removal of plastic hinge of piers, restoration of piers to their original locations, rehabilitation and reinforcement of bridge piers."
Through computer simulation, time-lapse photography and staff explanation, a complete picture of “post-earthquake bridge emergency repair” was presented.
In order to accomplish this exercise, THSRC mobilized its third-party manufacturers to dispatch 35-ton pallet trucks up to 100 trips. In addition, large-scale excavators, cranes, mobile cranes and auto levels and other large equipment were mobilized, taking 4 months to prepare for the exercise. The “Heavy duty steel support” and “H-steel” used in the exercise weighed up to 465 tons; cement and ready mixed concrete covered up to 200 m3. Observing units included TRA, RRB, Directorate General of Highways, Tainan City Government and CECI Engineering Consultants Inc., which all sent representatives to witness the “post-earthquake bridge emergency repair” large scale exercise held for the first time in Taiwan.
