Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tunnel construction safety early warning, more specifically, relates to a tunnel construction safety early warning method and system based on multi-dimensional data processing. BACKGROUND

[0002] Various types of disasters can occur inside the tunnel, mainly including water and mud inrush, collapse, rock burst, gas leakage, fire, structural cracking and deformation, lining falling, etc. These disasters can occur not only during the construction phase but also during the operation period, and have the characteristics of strong suddenness, high early warning difficulty and serious consequences. Water and mud inrush is usually caused by high permeability of surrounding rock, high groundwater pressure and incomplete closure of the working face, which can easily cause equipment damage and personnel casualties; collapse is often related to poor stability of surrounding rock, support failure or disturbance, and is one of the most common disasters in tunnels; fire can be caused by mechanical and electrical failures, flammable transportation, and is difficult to escape, and there is currently no technical solution to effectively early warn the above tunnel disasters.

[0007] According to the tunnel information, the real-time risk value of each position in the tunnel is calculated, the positions corresponding to the real-time risk values meeting the preset conditions are marked and connected to form an escape path, and the tunnel BIM model is mapped into the tunnel BIM model, and the tunnel BIM model is displayed in real time on a virtual reality device.

[0008] Further, the disaster type identification model adopts LSTM or Transformer structure, and the historical disaster data set corresponding to each disaster type is input into the LSTM or Transformer structure to complete the training of the disaster type identification model.

[0009] Further, the disaster type identification model is:

[0020] Furthermore, the disaster type identification model adopts an LSTM or Transformer structure, and the historical disaster data corresponding to each disaster type is input into the LSTM or Transformer structure to complete the training of the disaster type identification model.

[0021] Furthermore, the disaster type identification model is as follows:

[0022]

[0042] Among them, Π k (t) represents the predicted value (between 0 and 1) for the occurrence of the k-th type of disaster at time t, where n is the number of information variables, and ω i，k Let σ be the weight of the influence of the i-th information variable on the k-th type of disaster. i (t) represents the i-th information variable in the tunnel information at time t, γ i，k Let χ be the response factor of the i-th information variable in the k-th type of disaster. i (t) is the state evolution factor of the i-th information variable at time t, λ i，k Let δ be the anomalous response suppression coefficient of the i-th information variable to the k-th type of disaster. i (t) represents the offset of the i-th information variable at time t from the corresponding historical average information variable.

[0043] Preferably, γ i，k λ is used to control the sensitivity threshold of variables to disasters. For example, in a fire, the temperature must rise to a critical point before the corresponding disaster potential is activated. i，k It is used to control whether a variable is just a short-term fluctuation. For example, a sudden small fluctuation in water pressure is not the same as a sudden water outburst. It must deviate continuously to activate the corresponding disaster potential.

[0058] Preferably, in this embodiment, the real-time risk value at each location within the tunnel is calculated using the following formula:

[0059]

[0060] Where γ′(t) is the real-time risk value at the current position and time t, n′ is the number of state evolution factors, and ρ′ k′ χ is the weight of the rate of change of the k′-th state evolution factor. k′ (t) is the k′-th state evolution factor at time t, K k′ χ is the weight of the integral of the k′-th state evolution factor. k′ (τ) is the k′-th state evolution factor at time τ, Θ′ c This is the disaster trigger threshold.
