摘要：

Owing to several construction procedures of bidirectional 6 lane multi-arch tunnel, with the characteristics of large dig span and flat cross section, the wall rock and support structure of which will be repeatedly disturbed by multiple excavations, so their mechanical and deformational features are remarkably complicated. Combined with the design and construction practice of Sha Tangkeng bidirectional 6 lane multi-arch tunnel of Guang-He highway, taking the V grade surrounding rock for case, with the help of 3-dimension finite element numerical simulation method and 3-dimension physical similar model test, the paper studied the entire dynamic construction process of bidirectional 6 lane multi-arch tunnel, analyzed the chang characteristics of displacement and stress of wall rock and stress of supporting structure, and revealed the time-space effect laws of construction of bidirectional 6 lane multi-arch tunnel.
