Intellectual Merit: The buried and on-ground pipelines develop damage due to temporal variables such as corrosion and creep or instantaneous threats such as earthquake and impact. The detection of leaking oil, water or natural gas in the pressurized pipelines before reaching structural instability is important to prevent any catastrophic failure and, consequently, detrimental environmental impact. The objective of this BRIGE proposal is to prevent such failures of pipeline networks using a real time damage detection scheme for early diagnostics. The research approach is based on understanding wave propagation characteristics in steel and polymer based pipelines due to leak, damage and impact, and develop novel shear sensor in order to detect and locate the source based on propagating elastic waves. Novel piezoelectric based shear sensor will allow large sensor spacing for monitoring pipelines with a limited number of sensors. A new location algorithm will be implemented using the geometric connectivity of pipeline structures, which allows locating the source in multi-dimensions using one dimensional sensor array. The developed sensor and system will be validated in field testing. Broader Impacts: Successful implementation of the research will eliminate unexpected failures in pipeline networks. The results of this research will be shared with pipeline authorities and organizations in the field of pipeline inspection and safety in order to demonstrate that the engineering methods can prevent impending catastrophic failures as a way of increasing public safety and protecting environment. The educational outreach and broadening participation approaches of the research will be to educate and mentor selected students from underrepresented groups who can be pioneers in the future challenges of critical infrastructure design and analysis; add a special interdisciplinary technical elective course to the curriculum to address how sensing systems are being integrated into parts of civil structures to prevent catastrophic failures; and support the participation of high school students into the research to attract them to engineering.

智能优点：埋地和地面管道会因时间变量(如腐蚀和蠕变)或瞬时威胁(如地震和冲击)而损坏。压力管道在达到结构失稳之前检测到石油、水或天然气的泄漏，对于防止任何灾难性的故障，从而造成有害的环境影响是很重要的。Brige建议的目标是使用用于早期诊断的实时损伤检测方案来防止管网出现此类故障。该研究方法是在了解钢基和聚合物基管道中泄漏、损伤和冲击波传播特性的基础上，开发新型剪切传感器，以便基于传播的弹性波来检测和定位震源。新型压电式剪切传感器将允许较大的传感器间距，用于监测有限数量的传感器的管道。利用管道结构的几何连通性实现了一种新的定位算法，该算法允许使用一维传感器阵列在多维方向上定位信号源。所开发的传感器和系统将在现场测试中得到验证。更广泛的影响：这项研究的成功实施将消除管道网络中的意外故障。这项研究的结果将与管道检测和安全领域的管道当局和组织分享，以证明工程方法可以防止即将发生的灾难性故障，作为提高公共安全和保护环境的一种方式。这项研究的教育宣传和扩大参与方法将是：教育和指导从代表性不足的群体中挑选出来的学生，他们可以成为未来关键基础设施设计和分析挑战的先锋；在课程中增加一门专门的跨学科技术选修课，说明如何将传感系统融入土木结构的某些部分，以防止灾难性故障；以及支持高中生参与研究，以吸引他们学习工程学。
