On Safety Monitoring on Construction Data in Scenario of Service Gate Replacement for Drainage Tunnel
In the scenario of service gate replacement for drainage tunnel,construction safety monitoring faces problems such as inaccurate data,interference from outliers,and difficulty in accurately evaluating the stress state.Therefore,a safety monitoring method on construction data in the scenario of service gate replacement for the drainage tunnel is proposed.Through mechanical calculations,the stress value of the key section of the gate is determined and the bearing capacity of the gate structure is evaluated.The collected stress data is smoothed to re-move outliers and noise.Feature extraction technique is used to extract key features from the processed data,and the weighted processing algorithm is adopted to analyze the features comprehensively.The construction safety monitoring model is built,the monitoring data is fused,and the safety monitoring threshold is calculated.By comparing the probability of construction safety reliability with the safety monitoring threshold,the safety status of the construction is determined.The example analysis results show that the monitoring limit equilibrium rate ob-tained by the designed method is consistent with the benchmark value of high monitoring accuracy.
