Abstract:
The construction technologies for the shallow largespan underwater section of Xiangjian rivercrossing tunnel at Yingpan road are studied, and the excavation of the tunnel section is simulated by means of 3D model, so as to guarantee the construction safety and to select proper construction organization and proper construction method. The analysis on the calculation and monitoring data proves that the 14step excavation method, doubleshell support technology and transitional section excavation technology adopted in the tunnel construction are rational. For the sake of the construction technologies mentioned, the safety and stability of the shallow largespan section of Xiangjiang rivercrossing tunnel are guaranteed.
Key words: Xiangjiang rivercrossing tunnel, shallow cover, large span section, crosssection changing, grouting, doubleshell primary support, monitoring
