摘要
长期监测是获得结构状态信息的重要手段,而传感器是监测的核心器件。目前监测传感器种类繁多,各自适用环境与范围各异,给实际应用带来一定的困难。介绍了土木工程结构长期监测中的风速仪、温度、应变、位移和加速度等常用传感器的特点和适用范围,以便建立监测系统时进行选择;并就一些具有发展前景的传感器和监测方法进行了探讨,有利于促进学科发展。
Long-term monitoring is an important means of obtaining the state information of structures, and sensors are the core devices for monitoring. At present, there are various kinds of sensors available, which are quite different in their applicable en-vironment and application scope, owing to which certain difficulty happens to their practical application. Introduced in the pres-ent paper are the characteristics and the application scopes of common sensors for monitoring wind speed, temperature, strain, displacement and acceleration in order to facilitate the choice of them when a monitoring system is to be established. Mean-while, an exploration is also made into some of the sensors and monitoring methods that have the prospect of development, which may benefit the development of the subject.
