Research on deformation and control measures of TBM undercrossing buildings
In this paper, the finite element software is used to establish the calculation model of double-line TBM tunnel crossing buildings, and the influence of TBM construction on ground surface and buildings is analyzed. At the same time, the reinforcement effect of full-section curtain grouting reinforcement and advanced small pipe grouting reinforcement is studied. It provides the basis for the future development of smart city and the intelligent control of TBM crossing project, and provides reference for similar projects. The results show that:-l) The peak point of the surface subsidence trough will shift towards the fracture zone. 2) Building settlement deformation presents a trend of large in the middle and small at both ends. 3) With the increase of the number of layers, the settlement value of the frame column decreases gradually. 4) Better effect of full section curtain grouting reinforcement.
