【摘要】 埋入式传感器在混凝土结构的健康监测中应用日益广泛,但其有效寿命远低于结构的使用寿命,为了解决这一问题,尽管学者们对传感器的封装和保护方法做了很多研究和探讨,但是若不解决埋入式传感器的更换问题,对结构的全生命周期监测实际上是不可能的。本文介绍了作者最近完成的有关混凝土结构埋入式传感装置的新型专利技术,通过对老化的传感装置进行替换来使应变监测得以长期连续进行,从而简便可靠地解决了埋入式传感器的耐久性问题。为验证专利技术的可行性,设计了相关试验以证明其可行性和实用意义。本文所介绍的专利技术不仅可以实现传感器的替换,而且可以保证替换过程中的连续监测及替换后的测量精度。更多还原

【Abstract】 Embedded sensors have been widely used in the health monitoring of concrete structures.However,the serviceable life of the sensors is significantly less than that of concrete structures.Therefore,it is impossible for the sensors to monitor the whole life cycle of structures if embedded sensors can not be substituted.In the present paper,two kinds of new technique on installations of sensors are introduced,which can be used to substitute the aged sensors.To some extent,it is feasible to solve the durability problem of embedded sensors conveniently and reliably.更多还原
