tunnel ground subsidence

基本解释

The norms of the ground subsidence for tunnel construction allowed by ground structures, underground pipelines and metro are studied.
研究了地面建筑物、地下管线及地下铁道允许的隧道施工引起的地表沉降基准；
During the construction of shield machine, tail void grouting is a necessary and key procedure, which can actively control the tunnel uplift and ground subsidence.
对盾尾空隙进行注浆是盾构施工的必备及关键工序，由此达到控制隧道上浮及地面沉降。
Field observations showed that there are two major causes to shield tunnel during ground shaking: earthquake wave propagation and differential subsidence due to earthquake.
一是盾构法隧道结构在地震行波作用下的动力响应分析与抗震设计，二是盾构法隧道在不均匀震陷下的纵向受力研究与抗震设计。
