在开挖浅埋隧道的过程中,由于地层损失和地下水位变化会造成隧道上方的地表沉降,当地表变形超过一定限度时就会影响隧道或地表公路和建筑物的安全与正常使用。将某城际轨道工程开挖浅埋隧道的监测数据与有限元计算结果进行对比分析,得出浅埋隧道施工过程中上方公路的沉降值及其影响范围,可为当地隧道工程施工提供参考和借鉴。
在開挖淺埋隧道的過程中,由于地層損失和地下水位變化會造成隧道上方的地錶沉降,噹地錶變形超過一定限度時就會影響隧道或地錶公路和建築物的安全與正常使用。將某城際軌道工程開挖淺埋隧道的鑑測數據與有限元計算結果進行對比分析,得齣淺埋隧道施工過程中上方公路的沉降值及其影響範圍,可為噹地隧道工程施工提供參攷和藉鑒。

During the excavation of shallow buried tunnel, strata loss and the change of underground water level result in ground settlement above the tunnel. The ground deformation beyond a certain extent will influence the safety and normal operation of tunnel, surface highway and buildings. During the excavation of shallow buried tunnel in one intercity rail project, relevant data are monitored, which can be compared with the calculation result by finite element model. The analysis result involves the settlement value of overhead highway and the range of influence during the construction of shallow buried tunnel, which will provide references for local tunnel projects.
