跨铁路斜拉桥健康监测与安全评估系统的建立与应用

Establishment and Application of Health Monitoring and Safety Evaluation System for Cable-stayed Bridge Crossing Railway

摘要:

与普通公路桥梁养护检查相比，跨铁路桥梁评定的检查复杂度、难度更高，投入的养护资金也更多。依托某跨铁路斜拉桥工程，采用无线传感技术便捷部署桥梁健康监测系统，实现快速、低成本的桥梁状态评估，为桥梁养护维修提供客观依据，从而有效降低跨铁路桥梁定检频次，实现更精准的检测资金分配。

Abstract:

Compared with the maintenance and inspection of common highway bridge, the inspection complexity and difficulties in the evaluation of bridge crossing railway are higher, and the maintenance fund to be invested is also more. Relying on a cable-stayed bridge crossing railway project, the wireless sensing technology is used to conveniently and quickly deploy the bridge health monitoring system in order to realize the high speed and low cost of bridge state evaluation, which provides the objective basis for the maintenance and repair of bridges so as to effectively reduce the regular detection frequency of bridge crossing railway and to realize more accurate distribution of detection fund.
