摘要

對於公路穿越鐵路橫交工程結構，除採高架橋跨越外，另一方法即為下穿方式。惟下穿箱涵施工之同時仍須確保縱貫鐵路通車營運需求及行車安全，因此除在工法設計與施工管理上須要格外謹慎外，更必須與鐵路局相關單位充分協調配合，以確保安全與工期掌控。本文主要以明挖托底工法為主軸，將相關工法評估與設計作一完整彙集，並說明與鐵路局相關單位界面協調之重點及設計注意事項，最後並舉一個設計實例說明完整設計過程，期能提供後續相關工程設計之參考。

How to choose a suitable structural type is designed regarding a highway crossed by a railway? One way is adopting overpass, the other one is under through. When construction of latter is carried out, smooth of operation and safety of transport must be ensured. For these reasons, besides full care of design and management of construction must be given close attention, a full coordination with the related unit of Taiwan Railway Bureau is crucially important. This article is mainly about using open cut and underpinning method to solve this engineering problem. There is a complete collection of information regarding design and construction of this method, points to pay attention regarding interface coordination and attentive matter of design between designer and Railway Bureau and a complete design case. The objective of this presentation is to provide reference to all who are concerned when similar designs are encountered in the future.
