针对盾构隧道开挖引起的地表沉降问题,基于 GAP 法模型的基本原理,通过对该模型的改进,借助FLAC2D 进行数值分析,对盾构隧道的地表沉降规律进行了研究.得出了同一盾构直径随着隧道埋深增加的情况下,地表最大沉降值逐渐减小、地表沉降槽逐渐变宽的规律,且隧道埋深和地表最大沉降值存在某种线性关系.该成果对盾构隧道开挖引起的地表沉降分析具有一定的参考价值和指导意义.

@@@@To predict the ground settlement caused by shield tunneling, based on the GAP principle and improved model, this study investigates the characteristics of the ground settlement induced by shield excavation using FLAC2D numerical analysis method. The study results show that with the same shield diameter, when the tunnel depth increases, the maximum surface settlement gradually decreases and the settlement tank gradually widens. There is a linear relationship between tunnel depth and maximum surface settlement. This study results have some reference value and significance on the ground settlement analysis caused by shield tunneling.
