摘　　要：以重庆主城排水越江盾构隧洞工程为背景,对施工阶段外水压和使用阶段内0.7 MPa外水压条件下的盾构隧洞及其内部输水管道进行了数值模拟分析,得出了施工和使用阶段0.6～0.7 MPa结构的内力、变形和位移的大小与分布,通过研究探明了此复杂结构的受力特征,为工程的设计施工提供了重要依据.Based on the drain tunnel project crossing Yangtze River in the downtown of Chongqmg city, tins paper carries out the numerical simulation analyses under the conditions with external water pressure of 0. 7MPa during construction period and internal water pressure from 0.6 to 0.7MPa during operation, in consequence, the magnitude and distribution of internal forces, deformations and displacements are obtained respectively for the construction and operation period. The performance of the complicated structure was highlighted through the analyses which provided the basis for the design and construction of this project.
