摘要
Recently, more and more shield-driven construction projects have to cross over or under the existing metro line in soft soil in China. To evaluate the influence of such construction, three major factors were studied in this article based on monitoring data. They were the vertical interval between the two tunnels, the projection angel and the synchronous grouting rate. The linear regression formulas were also obtained to show the trends of displacement during the overcrossing and the undercrossing construction projects.
