Analysis of Microtremor Exploration Application and Construction Monitoring in a Large-Diameter Shield Tunnel

In recent years, shield tunneling has shown many advantages with the development of underground rail traffic. Geological exploration plays a significant role in tunnel engineering, and detailed geological results can guide successful construction tunnel. This research relies on super large-diameter construction, using microtremor technology to collect data onsite. Combined comparative analysis borehole surveying, reliability is verified. Moreover, monitoring result impact slurry balanced surrounding environment analyzed. The show that obtain details traditional detection methods cannot obtain, which predict possible local geology mutation front advance. law surface settlement curve conforms Peck formula. be divided into five stages: micro deformation, extrusion uplift, reciprocating detachment settlement, consolidation settlement. eccentric loads side more prominent. maximum pressure outside segment appears lower section, approximately 0.41 MPa, will increase grouting become stable days.
