GOALI: An Innovative Real Time Bridge Scour Sensor for Bridge Risk Management

该GOALI提案的重点是在关键洪水事件期间开发一种真实的实时的创新型桥梁冲刷监测系统。桥梁冲刷是指桥墩或桥台附近土壤的侵蚀，是桥梁破坏的头号原因。将研制一种集成微功率脉冲技术（MIR）和能量收集技术的自供电自动桥梁冲刷传感器。 该传感器的性能将在模拟实验室实验和现场试验台上的原型桥梁结构上进行验证。智力优势该项目将通过为洪水条件下桥梁的安全监测提供创新的桥梁冲刷传感技术，为支持科学研究和实践设计做出独特的贡献。 监测数据还可以帮助校准和改进现有的冲刷预测理论和风险估计。 这将确保安全和经济的冲刷对策的部署。更广泛的影响这项研究将建立在一个强大的伙伴关系，使学术界和私营企业联手，并解决关键的国家需求。此外，该教育计划将联合收割机将研究工作与积极的外展活动结合起来，让K-12学校的学生参与民用基础设施研究。

This GOALI proposal is focused on developing an innovative bridge scour monitoring system in real time during the critical floods events. Bridge scour, which refers to the erosion of soil adjacent to bridge piers or abutments, is the number one cause of bridge failures. An automatic bridge scour sensor that is self-powered through integration of micropower impulse technology (MIR) and energy harvesting will be developed and fabricated. The sensor performance will be validated on a prototype bridge structure in simulated laboratory experiments and on field testbed.Intellectual MeritsThis project will make unique contributions to support scientific study and practice design by providing innovative bridge scour sensoring for safety surveillance of bridges in flood conditions. The monitoring data can also help calibrate and improve the existing scour prediction theory and risk estimation. This will ensure the deployment of scour countermeasures that are safe and economic.Broader ImpactsThis research will built upon a strong partnership that allows for the academia and private industry to join force and address critical national needs. Additionally, the education plan will combine the research effort with aggressive outreach activities to involve students in K-12 schools in civil infrastructure research.
