摘要：

Seepage field has a great influence on stress field of shield tunnel structure during construction under high water pressure. The FEM has been used to analyze the coupling seepage field and stress field under different water pressures based on the drainage tunnel project crossing the Yangtze River at the downtown of Chongqing city. The segment's stress distribution, displacements and pore pressure distributions are calculated. Water pressure distributing rule has been studied emphatically; and the results are verified by the in-situ data. The calculation show that segments need to take more tensile force under coupling effect. The achieved results offer helpful reference and basis for design and construction of this project.
