Abstract
Based on a domestic engineering of metro shield tunneling underneath existing buildings, the article uses finite element analysis software Plaxis to simulate the whole process of shield tunnel excava-tion, analyzes the subsidence problems caused by the construction. The research result shows that:when tunneling underneath residential buildings, pile foundation will produce larger uneven settlement; when tunneling underneath boiler room, foundation settlement is beyond the control;there are significant risks in the process of tunneling construction successively under residential buildings and boiler room. Techni-cal measures during shield tunneling are put forward to control structure settlement effectively and achieve related safety requirements.关键词
