1) The double-hole parallel tunnel
双孔并行隧道
2) twin-parallel-tunnel
双孔平行隧道
1.
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.
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。
3) parallel tunnel
并行隧道
