摘要
高速公路横向下穿隧道施工,易诱发上方路面沉降,尤其是不均匀沉降,影响公路正常运营。结合某倒吸虹隧道支护结构设计和施工方案,运用数值模拟分析手段,对下穿隧道施工进行了三维动态数值模拟,重点分析了隧道建设对上方高速公路路面沉降的影响,评估了隧道支护结构设计和施工方案的可行性。
The expressway normal working is easy to be influenced for the road surface uneven settlement induced by the under-traverse tunnel construction. Based on some tunnel support design and construction scheme, the 3D tunnel staged construction mechanics was studied by using the numerical method. The expressway road surface uneven settlement was emphatically analyzed and the feasibility of the tunnel support structure design and the construction scheme was assessed.
