TUNNEL CONSTRUCTION METHOD BY ABNORMAL WIND PRESSURE DISSOLVING BUFFER METHOD ADAPTED TO SUPERHIGH-SPEED RAILWAY AGE AND BY PERMANENT REMAINING METHOD OF CONCRETE FORM BASED ON NEWLY DEVELOPED DESIGN

摘要

PROBLEM TO BE SOLVED: To eliminate intensive rolling caused by abnormal wind pressure generated when a high-speed train enters a tunnel.;SOLUTION: A tunnel entrance is formed in a curved surface wall body structure shape similar to a daffodil, and a form using a flexible material (such as a synthetic rubber material) is used as a permanent form (a form not removed after concrete placing) for construction.;COPYRIGHT: (C)2005,JPO&NCIPI
