摘要
既有隧道上方大量的土体堆载会对隧道结构受力产生不利影响,导致隧道管片开裂等情况发生。本文将理论计算与数值模拟方法相结合,分析了既有圆形隧道顶部堆载情况下的结构受力情况,以期对既有隧道的保护提供参考依据。
The large amount of soil mass loading above the existing tunnel will have an adverse effect on the structural force of the tunnel,leading to cracking of tunnel segments.By combining the theoretical calculation and numerical simulation method,this paper analyzes the structural force conditions of the existing top-loaded circular tunnel with a view to providing a reference for the protection of the existing tunnel.
