Numerous accidents have shown: besides the technical problem of construction, the subjectivity of manual identification risk is high, the spatial positioning of underground construction is inaccurate, and information transmission is not timely and inaccurate, which are also important factors restricting risk control. Therefore, a safety risk management and control platform based on three-dimensional visualization needs to be established in the construction process so as to scientifically, comprehensively, dynamically and visually master the safety risk in the subway construction process and assist in engineering management and leader decision-making.
Most of the existing risk early warning methods based on the shield real-time monitoring system depend on manual judgment of the position relationship between a risk source and a tunnel, and are not accurate and visual enough; when construction is close to a risk source, automatic prompt cannot be given, and management personnel may miss part of the risk source.
