| 摘 要： | 针对现常用的健康监测系统中不能解决诊断混凝土桥梁结构初始裂纹的产生和发展状况,在混凝土桥梁裂纹仿生监测原理基础上,模拟生物体的神经元及神经脉络分布对生物体内部或外部各个局部变化(如开裂)的感知机制,实现对混凝土桥梁结构关键区域的裂缝监测.分别从试验和断裂力学理论两方面证明了裂缝仿生监测机敏膜能够监测混凝土桥梁的裂缝.试...

| Abstract: | In the concrete bridge structural health monitoring,one of the most important problems is the crack identification.For commonly used health monitoring systems cannot solve the diagnosis of the emerge and development of initial cracks in concrete bridge structure,the basic idea of smart film for bionic crack monitoring was introduced to simulate the distribution of neurons and neural context of organism for perceiving all local changes(e.g.,cracking) of internal or external organism for the realization of mo... |
