大桥斜拉索索力监测数据

本数据来源于对大桥斜拉索的索力检测，利用大桥斜拉索索力监测数据，监测桥梁索力异常波动，通过索力数据模型分析，智能提示巡检、维护、维修等建议及方案。根据桥梁索力设计允许参数，结合长期监测数据，将安全范围内但超过平均值的监测数据，按超过平均值的百分比分成4个等级，求得每条斜拉索的索力异常阀值，分别为：
一级异常=(容许索力-监测平均索力)×10%+监测平均索力；
二级异常=(容许索力-监测平均索力)×20%+监测平均索力；
三级异常=(容许索力-监测平均索力)×30%+监测平均索力；
四级异常=(容许索力-监测平均索力)×40%+监测平均索力；
在日常监测过程中，将实时监测获得的当前索力与索力异常阀值进行比较，系统将提供“无、关注、巡检、维护、检修”5个等级的维护建议，并记入大桥斜拉索索力监测数据中，如：
当前索力值位于一级异常阀值以下时，状态为“正常”，维护建议为“无”；
当前索力值位于一级异常阀值和二级异常阀值时，状态为“一级异常”，维护建议为“关注”；
当前索力值位于二级异常阀值和三级异常阀值时，状态为“二级异常”，维护建议为“巡检”；
当前索力值位于三级异常阀值和四级异常阀值时，状态为“三级异常”，维护建议为“维护”；
当前索力值位于四级异常阀值以上时，状态为“四级异常”，维护建议为“检修”。

This dataset is established based on cable force detection for bridge stay cables. Leveraging long-term monitoring data of stay cable forces, the system detects abnormal fluctuations in bridge cable forces, and provides intelligent suggestions and solutions for inspection, maintenance and repair via cable force data model analysis. Based on the design allowable parameters of bridge stay cable forces and combined with long-term monitoring data, monitoring data within the safe range but exceeding the average value are categorized into 4 levels according to the percentage by which they exceed the average cable force, thereby deriving the cable force abnormality thresholds for each individual stay cable. The thresholds are defined as:
Level 1 Abnormality Threshold: (Allowable Cable Force - Monitoring Average Cable Force) × 10% + Monitoring Average Cable Force;
Level 2 Abnormality Threshold: (Allowable Cable Force - Monitoring Average Cable Force) × 20% + Monitoring Average Cable Force;
Level 3 Abnormality Threshold: (Allowable Cable Force - Monitoring Average Cable Force) × 30% + Monitoring Average Cable Force;
Level 4 Abnormality Threshold: (Allowable Cable Force - Monitoring Average Cable Force) × 40% + Monitoring Average Cable Force;
During daily monitoring, the real-time current cable force obtained from monitoring is compared against the pre-determined cable force abnormality thresholds. The system will then generate 5 levels of maintenance recommendations, namely "No Action Required", "Pay Attention", "Inspect", "Maintain", and "Overhaul", which are recorded in the bridge stay cable force monitoring dataset. Specific cases are listed below:
1. When the current cable force is below the Level 1 Abnormality Threshold, the status is marked as "Normal" and the corresponding maintenance recommendation is "No Action Required";
2. When the current cable force falls between the Level 1 and Level 2 Abnormality Thresholds, the status is "Level 1 Abnormality" and the maintenance recommendation is "Pay Attention";
3. When the current cable force falls between the Level 2 and Level 3 Abnormality Thresholds, the status is "Level 2 Abnormality" and the maintenance recommendation is "Inspect";
4. When the current cable force falls between the Level 3 and Level 4 Abnormality Thresholds, the status is "Level 3 Abnormality" and the maintenance recommendation is "Maintain";
5. When the current cable force exceeds the Level 4 Abnormality Threshold, the status is "Level 4 Abnormality" and the maintenance recommendation is "Overhaul";
