摘要
使用基于弹塑性增量理论的有限元法,采用三维有限元模拟了隧洞接近立交桥挖孔桩的施工过程,并考虑了支护混凝土和注浆地层力学参数随龄期的变化等因素,得到对设计和施工具有参考价值的结论。
This paper studies the tunnd construction adjacent to existing pile foundation . Two tunnels are embedded in soft ground under road. The construction process of tunnels adjacent to boring piles is simulated with the 3-D nonlinear finite element method in details, considering the material properties changing with time.
