Research on construction optimization of asymmetric double arch section in Jiaozhou Bay Subsea Tunnel

Wang Kai,Zhang Chengping,Wang Mengshu

Strategic Study of CAE 2012, Volume 14, Issue 1,   Pages 90-97

Abstract:

Aiming at the asymmetric double-arch tunnel engineering that lies at Jiaozhou Bay in Qingdao, the section located in the intersection between main tunnel and ramb tunnel is chosen as a typical cross section and a three-dimensional model for numerical analysis. Four construction schemes are constituted according to different construction sequences and different digging lengths. Then these schemes are simulated with FLAC3D program. By analyzing ground surface settlement, vault settlement values, displacement of supporting structure, principle stress in surrounding rock, as well as principle stress in supporting structure, the most disadvantage position of structural deformation and stress during construction is determined. It concludes that the surrounding rock deformation could be better controlled by using of the construction sequence that first middle drift and then right hole of ramb tunnel, and the reasonable construction scheme is suggested.
