辽宁沈阳地区冻土深度自动观测方法研究
|
摘要
文章利用沈阳观测台站2007～2017年的冻土及深层地温的观测记录和2015年冻土自动观测设备与人工对比试验的观测数据,从温度变化因子对冻土自动观测设备的动态响应特性进行了研究分析。结果表明:季节性冻土的最大冻结深度与温度变化因子有一定的相关关系,在分析自动观测仪器的响应特性和传感器静态测试时,应考虑由热力因子之间,尤其是气温和直接接触传感器的温度之间的环境变化过程对冻结深度的影响及传感器响应带来的线性度和灵敏度的变化。
By using the observational data of frozen soil and depth soil temperature in Shenyang observation station from the year of 2007 to 2017,and by means of comparing observed data between automatic and manual observation methods,this paper studies and analyzes the dynamic response characteristics of automatic observing frozen soil equipment based on temperature change factors.The results show that there is a certain correlation between the maximum seasonal frozen depth and temperature change factors.When analyzing response characteristics and sensor's static test of automatic observation instrument,it should be considered the influence of the environmental change between the thermal factors,especially between the temperature and the direct contact sensor on the freezing depth and the linearity and sensitivity of the sensor response.
