Abstract
930 Subway station in Seoul Subway line #9 is under construction underpassing Seoul Subway line #2 which is the only circulation inSeoul Metropolitan. This study verified the application of the temporary bridge bearing method which is used to station constructionunder existing Subway line #2 of Subway line #9 construction. Temporary bridge bearing method was conducted using an numericalanalysis calculated FEM program MIDAS CIVIL of the verified proposed Method by monitored through heavy instrumentation systemduring construction. The upward movement from removing loads on structure is usually not considered in design. The upwardmovement is not an important factor for the stability of structure due to the small amounts of movement. However, it is not ignoreablefor the safety of railway operation, since the upward movement of rail is considered to be one of the most dangerous factors forsafety in railway. Therefore, the upward movement characteristic should be considered for railway projects. The proposed method canbe used for similar project with stability confidence and cost savings through the verification procedure from this research.
