Abstract: Taking shield tunnel between Hohhot Station and Gongzhufu Station of Hohhot City Rail Transit Line 2 undercrossing masonry structure residential group as engineering background, numerical simulation for shield tunnel undercrossing masonry structure residential group is carried out by using MIDAS\|GTS finite element software. The maximum tensile stress increment of the masonry structured house wall is taken as the evaluation index. The influence of shield tunnel construction on masonry structured house is analyzed, and technical parameters are proposed for deep\|hole grouting reinforcement measure. The reinforcement effect is analyzed taking into consideration of field monitoring data. Results show that, without reinforcement measure, settlement of house can meet control requirements, but the maximum tensile stress increment of masonry structure wall does not meet the requirements of safe use after shield tunnel construction completed; with deep\|hole grouting reinforcement technology, the maximum tensile stress increment of the wall can meet safe control standards of building. It is proved that the deep-hole grouting reinforcement technology can well reduce the influence on masonry structure caused by shield tunnel construction and ensure safe and normal use of masonry buildings.
