摘　　要：土木工程在施工和运营中时常发生事故。传统的监测和预警方法反馈不及时不直接,往往错失事故防范的最佳时期。针对传统监测和预警方法的局限性,研究了风险可视化的监测预警方法。该方法通过传感器获取量测信息,通过微处理器对量测信息进行处理分析,综合评判工程的风险等级,控制LED(Light-Emitting Diode,发光二极管)显示不同颜色,实现及时预警以保证工程安全。介绍了土木工程风险可视化监测预警方法的概念、基本原理以及其在土木工程各领域内的应用,同时开发了风险可视化监测预警系统原型,并进行了室内试验。Accidents of civil engineering happen a lot during construction and operation.The traditional method of monitoring and pre-warning cannot get feedback in time and directly;it often misses the best opportunity to prevent disasters.In order to solve this problem,this paper presents a new monitoring and pre-warning method of risk visualization,which receives measuring information with sensors,analyzes the information with microcomputers to get the risk level of the project,and then changes the color of LED（Light-Emitting Diode）to represent the pre-warning information and ensure the safety of engineering.This paper introduces the concept,the basic principle of risk visualization,and its application in each areas of civil engineering.A prototype of risk visualization system has been developed,and indoor demonstration has been performed.
