「鐵路橋梁設計規範檢討修訂暨鐵路橋梁之檢測及補強規範草案研訂」委託技術服務案辦理情形 Implementation of the “Draft Development of Regulation for Rail Bridge Designs Amendment and Regulations for the Detection and Reinforcement of Railway Bridges” Technical Service Case

依交通部104年3月19日第1604次部務會報結論,通盤檢討部頒橋梁規劃設計規範導入橋梁全生命週期的概念,爰交通部於104年3月31日函請本局研議橋梁全生命週期設計規範制定事宜、104年5月1日函請本局以橋梁全生命週期概念為主軸,就鐵路橋梁安全評估(如耐震、耐沖刷能力等)與補強作業之相關規範進行通盤檢討。
橋梁之生命週期大致可分為規劃、設計、施工、維護等階段,橋梁相關規範要導入橋梁全生命週期概念,應同時考慮橋梁各階段之特性及需求,訂定從規劃設計、施工至維護階段的辦理準則,以達到增加橋梁壽齡及橋梁全生命週期成本最小化之目標。
因橋梁生命週期各階段互有關聯影響,爰本局同時檢討修訂設計階段及維護階段二規範,於105年5月11日委託台灣世曦工程顧問股份有限公司辦理,工作包含一、全面檢討修訂「鐵路橋梁設計規範」,二、研訂「鐵路橋梁之檢測及補強規範(草案)」,內容包含既有部頒之「鐵路鋼結構橋梁之檢測及補強規範」,並新增鋼筋混凝土橋梁之檢測及補強規範部分,使鐵路橋梁全生命週期各規範更加完備。
本案規範草案之檢討修訂過程中,除了辦理專家學者座談會廣徵各專家學者的意見外,規範草案研擬完成後並依部頒技術規範作業機制辦理規範草案初審作業。本案業於106年11月11日完成期末報告定稿及規範草案(含解說),並已提送二規範草案報部複審。

According to the conclusion of the 1604th MOTC Ministerial Meeting on Mar. 19, 2015 that conducted an overall review of introducing the concept of bridge life cycle into bridge planning and design, MOTC invited BOHSR to discuss the regulations of the matter on Mar. 31, 2015. On May 1 2015, MOTC asked BOHSR to conduct a general review of the relevant norms of railway bridge safety assessment (such as earthquake resistance and erosion resistance) and reinforcement work based on the concept of bridge life cycle.
The life cycle of the bridge can be broadly divided into stages of planning, design, construction and maintenance. To introduce the concept of bridge life cycle into bridge-related norms, the characteristics and requirements of all phases of the bridge should be taken into account. Then, guidelines for planning, design, construction and maintenance will be set so as to achieve the goal of increasing the service life of bridges and minimizing the total costs of bridge life cycles.
Due to the mutual influence of all stages of the bridge life cycle, BOHSR simultaneously reviewed and revised the regulations of both the design phase and maintenance phase. On May 11, 2016, BOHSR entrusted CECI Engineering Consultants Inc. to implement the assignment. The assignment includes: 1. To fully review and revise the “Regulations for Rail Bridge Designs”, and 2. to formulate the “Regulations for the Detection and Reinforcement of Railway Bridges (Draft)”. Regulation contents included the existing ministerial “Regulations for the Detection and Reinforcement of the Steel Structures of Railway Bridges” and additional sections for the testing and reinforcement of RC bridges so as to make the norms of the entire life cycle of railway bridges more complete.
In the process of reviewing and revising the draft of the regulations, BOHSR solicited opinions from experts and scholars on relative symposiums to complete the normative draft. Then, the initial inspection work of the draft will be implemented according to the ministerial technical standard mechanism. On Nov. 11, 2017, the final report and normative draft (inclusive of narratives) have been completed and have already been submitted to MOTC for secondary review.
