AI Technical Summary
Traditional underground tunnel construction near existing buildings lacks systematic integration and precise calculation, which can easily lead to instability of the surrounding rock or excessive deformation of the building during construction, affecting construction efficiency and safety, and failing to meet the refined and safe requirements of modern underground engineering.
By receiving construction instructions, calculating the tunnel area adjustment coefficient, confirming the target construction area, determining the stable bearing layer by combining the geological columnar section, dynamically adjusting the prohibited construction area, setting up monitoring points using the fitting circle method, monitoring in real time, triggering closed-loop remediation through calculation, selecting the construction method of support before tunneling or tunneling before support, and optimizing the construction process.
It improved construction efficiency and quality, ensured the safety of existing buildings, reduced unnecessary avoidance areas, and enhanced the usability and adaptability of the construction area.
