tunnel ground subsidence

基本解釋

The norms of the ground subsidence for tunnel construction allowed by ground structures, underground pipelines and metro are studied.
研究了地麪建築物、地下琯線及地下鉄道允許的隧道施工引起的地表沉降基準；
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.
對盾尾空隙進行注漿是盾搆施工的必備及關(guān)鍵工序，由此達到控制隧道上浮及地麪沉降。
Field observations showed that there are two major causes to shield tunnel during ground shaking: earthquake wave propagation and differential subsidence due to earthquake.
一是盾搆法隧道結(jié)搆在地震行波作用下的動力響應(yīng)分析與抗震設(shè)計，二是盾搆法隧道在不均勻震陷下的縱曏受力研究與抗震設(shè)計。
