摘要
利用信阳台长期、连续、可靠的定点形变观测数据,选取本台SSY伸缩仪2017年10月至2018年4月上半年观测数据,总结了时段内影响SSY伸缩仪观测资料的主要干扰因素,其反映在观测曲线上主要特征为大幅度阶跃变化,从降雨、降雪、洞温变化影响三个方面进行了具体分析,并进行了干扰因素总结,为同时段形变数据跟踪异常核实工作打下了良好基础,也为台站人员提供了有益的参考。
Based on the long-term, continuous and reliable fixed-point deformation observation data of Xinyang Station, the main interfering factors affecting the SSY stretcher observation data during the period from October 2017 to the first half of April 2018 are summarized. The main characteristics of the interfering factors are large-scale step changes in the observation curves, including rainfall and snow. And the influence of tunnel temperature variation on three aspects is analyzed concretely, and summarizedthe interference factors, which lays a good foundation for the verification of deformation data tracking anomaly in the same period, and also provides a useful reference for station personnel.
