Abstract:

Based on the analysis of the shield machine's crossing Yuanmingyuan station on metro line No.4 in Beijing, this paper discusses mainly the adjustment of the shield axis, the change of support structure and the reinforcement of the ends of station. And, the technical difficulties in the construction of subway station are researched because the shield machine crosses the station before the station begins to construct. At last, the technical measures are presented in this paper.

Key words: shield machine's crossing station, difficulty, technique measure
