摘要
将双孔平行隧道开挖引起的地表下沉视为一随机过程,应用随机介质理论,对隧道施工所引起的地表沉降进行分析,可推导出不均匀收敛模式下的计算公式。工程实例分析表明,该方法效果良好,具有一定的实用价值,可为同类工程提供参考。
The ground surface settlement due to twin-parallel-tunnel excavation is considered a stochastic process and the stochastic medium theory is applied to predict and analyze the ground settlement due to tunnel construction. The corresponding calculation formulas are derived. An example shows that the prediction method can get good results and has some practical value. It can provide reference for similar engineering.
