Abstract
In the paper, the segment assembling techniques of large-diameter shield were summarized, and the apparent damage reasons and repair technology of large-diameter shield reinforced concrete segment in the construction were preliminarily analyzed, based on research of the underground diameter project from Beijing railway station to Beijing railway west station. The different repair methods were proposed for the segments above hance and below hance, respectively, assuring the good strength and surface quality of large-diameter shield segment.
