[0004] For the sake of simplicity, when determining the data weight of tunnel monitoring points, it is assumed that all monitoring point data values have the same weight. This equal weight determination method reduces the importance of some monitoring data and cannot fully reflect the importance of each monitoring data. The contribution rate is not conducive to correctly assessing the security behavior of the tunnel, and there is an urgent need for a method to reasonably determine the data weight of tunnel monitoring points

The invention discloses o a method for determining weights of tunnel monitoring point data, and relates to the technical field of safety risk assessment. The method comprises the following steps of (1) performing initial weight assignment on measuring point data of the same step in an extensometer according to different distances from a tunnel; and (2) performing distance reduction on different measuring point data in the same extensometer so as to obtain updated weight assignment. According to the method, the distances between different steps of measuring points in different extensometers and the surface of the tunnel are considered, so that the contribution rate of different measuring point monitoring data to the safety of the tunnel is quantified, the potential safety hazard that a traditional equal-weight assignment method assumes that each tunnel monitoring data value has the same weight is overcome, the monitoring data have reference significance, effective information of tunnel monitoring points can be deeply excavated, and the safety of the tunnel is powerfully guaranteed.
Description
technical field [0001] The invention relates to the technical field of safety risk assessment, in particular to a method for determining data weights of tunnel monitoring points. Background technique [0002] Tunnel monitoring and measurement is an indispensable technical measure in the process of tunnel construction. Based on a large amount of monitoring data obtained by monitoring equipment, engineers and technicians evaluate the safety status of the tunnel and adjust the construction plan when necessary to ensure the safety of tunnel construction. [0003] When using tunnel monitoring data to evaluate tunnel safety performance, it is necessary to reasonably determine the weight of monitoring point data at different locations. This is because the data acquired by different monitoring points represent the indicators of different positions in the tunnel, and their contribution rates in the data analysis process are different. Therefore, the research on the method of determin...
