摘要
静冰压力是指冰层在升温膨胀受到约束的条件下,对约束体产生的压力.它是高寒地区水工建筑物的一种特殊载荷,也是冰科学和冰工程研究中最关键的物理指标之一.主要介绍了几种测量与确定静冰压力的方法及其存在的问题,并着重研究了适合测量静冰压力的光纤光栅传感器的工作原理和结构设计,提出了静冰压力在线检测系统的设计方法,解决了光纤光栅压力传感器的温度补偿问题.通过初步的研究表明,基于光纤光栅的静冰压力传感器具有尺寸小、分布式绝对测量、抗腐蚀能力强、抗干扰、适合于定点连续自动监测等优点.
Static ice pressure refers to the resulting pressure,which produced by the ice in the heat expansion of constrained conditions.It＇s a special load of cold area,and also one of the key physical parameters of ice science and engineering research.This paper mainly introduces several method of measurement and determination of static ice pressure and its existing problems,and especially studies the working principle and design method of fiber Bragg grating（PBG） which is suitable for measuring static ice pressure,and solved the problem of temperature compensation of the fiber Bragg grating pressure sensor as a result.Preliminary study shows that static ice pressure sensor based on fiber Bragg grating has the advantage of a small size,absolute distributed measurements,strong corrosion resistance,anti-interference,suitable for continuous fixed-point automatic monitoring,etc.
