摘要

白石湖悬索桥的主体结构通过三根主钢缆与锚碇基础相连。木制人行甲板使用钢梁固定在主钢索上，并由两根稳定缆索进行稳定。稳定索和桥身由44根钢连接杆连接。因此，主缆索锚固基础的边坡稳定性，以及主缆索和稳定缆索的性能监测和分析，对悬索桥的整体性能至关重要。本文讨论了该桥的钢索挠度和缆索强度的性能监测与分析，以及两岸桥台和边坡稳定性分析的主要考虑因素和结果。水位观测井、倾斜仪和倾斜仪监测用于记录参考数据，用于分析边坡稳定性性能。此外，还使用三维动力分析程序VFIFE对桥梁的变形和运动进行了分析。最终稳态结果用于比较静态设计值和监测数据。还观察到了在最终稳定状态之前的动态响应。

CASE STUDY ON PERFORMANCE MONITORING AND STABILITY ANALYSIS OF BAISHIHU SUSPENSION BRIDGE AND SIDE SLOPE

The main structure of the Baishihu suspension bridge was connected to the anchor foundations by three main steel cables. The wooden pedestrian deck was fixed to the main steel cables using steel beams and was stabilized by two stabilizing cables. The stabilizing cables and bridge body were joined by 44 steel connecting rods. Therefore, the slope stability at the anchorage foundations of the main steel cables, as well as the performance monitoring and analysis of the main steel cables and stabilizing cables, are critical to the overall performance of the suspension bridge. This paper discusses the performance monitoring and analysis of the steel cable deflection and cable strength for this bridge, as well as the main considerations and results of the stability analysis of the bridge abutments and side slopes of the two banks. Water-level observation wells, inclinometers, and tiltmeters monitoring were used to record reference data for the analysis of the slope stability performance. Additionally, the three-dimensional dynamic analysis program VFIFE was used to analyze the deformation and motion of the bridge. The final steady-state results were used to compare the static design value and monitoring data. The dynamic response before the final steady state was also observed.
