【摘要】 混凝土结构要实现服役智能化必须具备环境自感应、健康自监测和损伤自适应的功能。这无法在传统的土木工程学科自身范围内予以解决,还涉及到了力学、物理、化学、数学、材料、计算机、信息、传感器等诸多领域。结合该课题组近几年的相关研究,该文就混凝土结构服役智能化的两个专题进行了介绍和讨论:一是机电阻抗法用于混凝土结构健康监测的理论与实验研究:二是新型传感器特性及相关问题的研究。即使对这两个专题进行较深入的研究也将牵涉到不同的学科、方法和物理尺度,因此混凝土结构服役智能化的最终实现将极大地依赖于学科的交叉与综合,依赖于世界科技的整体发展水平。最后给出了若干研究展望。

【Abstract】 To achieve intelligentization for concrete structures during their service time,they must own the abilities of self-sensing of environments,self-monitoring of structural health,and self-adapting to damage.This goal can not be achieved within the conventional civil engineering discipline,and vast knowledge related to mechanics,physics,chemistry,mathematics,material engineering and science,computer science,information,and sensor is required.Based on the research conducted by our group in recent years,this paper introduces and discusses two special topics of the concrete structures intelligentization,i.e.the electromechanical impedance method,which has been developed and used in structural health monitoring in the last two decades;and the sensor technology,for which emphasis is placed on the most recent advances.The study of these two special topics also requires knowledge from different disciplines,different methods,and different physical scales.Thus,the actualization of intelligent concrete structures depends largely on the intersection of disciplines and their integration,especially on the global developing level of the world science and technology.Prospects on the research of intelligent concrete structures are finally presented from a personal point of view.
