交通–电力暗挖隧道共建方案优化研究

Optimization on Co-Construction Scheme of the Traffic and Power Tunnel

摘要: 结合重庆同茂大道金竹湾市政交通隧道与电力隧道共建工程，在理论分析的基础上，针对提出的两种施工方案，建立二维有限元模型，对其交通–电力隧道共建方案下围岩的塑性区半径、弹塑性交界处的应力以及弹塑性位移进行对比分析，提出较佳的共建方案。

Abstract: Based on the theoretical analysis of the Jinzhuwan municipal traffic tunnel and power tunnel co-construction project of Tongmao Avenue in Chongqing, a two-dimensional finite element model is established for the proposed two construction schemes, and the traffic-electricity tunnel co-construction scheme is selected. The plastic zone radius of the rock, the stress at the elastoplastic interface and the elastoplastic displacement are compared and analyzed, and a better co-construction scheme is proposed.
