摘要
钢筋参数(位置、直径等)对于已建建筑的安全性具有非常重要的作用。提出了一种利用太赫兹波检测建筑物内钢筋位置和直径的方法, 选取太赫兹波作为检测信号, 利用太赫兹波对非金属的建筑实体(如水泥、砖、石灰等)有着较强的穿透性以及对金属(钢筋)几乎全反射的特性,实现太赫兹波穿透建筑实体检测钢筋的功能。同时相对于微波而言太赫兹波易于实现极窄的天线波束, 从而达到很高的检测精度, 相对于磁感应仪而言其不受外界磁场环境的影响。经理论分析与工程实验表明, 该方法完全能够满足实际工程应用中的检测要求。
Abstract
The parameters of steel bar (such as position, diameter, etc.) play an important role in the safety of the constructed buildings. A measurement method for position and diameter of the steel bar within the building by using terahertz wave was proposed. The terahertz wave was used as the detection signal to realize these functions, which the terahertz wave had a strong penetrability to nonmetal building material (such as cement, brick, lime, etc.) and had the characteristics of almost total reflection to the metal (steel bar). At the same time, compared with the microwave, the terahertz wave was easy to achieve a very narrow antenna beam, which achieved high detection accuracy. And compared with the magnetic detector, it was not influenced by the external magnetic field environment. Theoretical analysis and engineering test show that this method can meet the requirements of actual engineering application.
