供水隧道下穿高速公路地层加固措施分析

Analysis on Water Supply Tunnel Underpass Expressway Ground Reinforcement Measures

基于数值模拟,对供水隧道下穿高速公路施工时,不同地层加固措施对上方公路沉降产生的影响进行分析,对沉降模拟结果进行比对,选择最优方案,降低施工风险,保证高速公路正常运营。

Based on numerical simulation, this paper has analyzed the impact that different highway subsidence ground layer reinforcement measures have on upper expressway subsidence during construction of water supply tunnel underpass expressway to compare the results of subsidence simulation, to choose the best alternatives, to reduce the construction risks and to ensure regular operation of expressway.
