摘要

通过对腾冲台钻孔应变近五年(2017年1月-2022年3月)观测日均值进行自检曲线分析,认为其观测资料稳定、数据真实可靠.对数据干扰源进行总结归纳,得出影响钻孔应变数据变化的主要干扰因素分别为放水蓄水干扰、降雨干扰、气压突变干扰与重型机械施工干扰等.对腾冲台钻孔应变数据资料进行同震响应分析,结果表明:该测项资料同震响应良好,与地震波形记录有较好的对应性.

Abstract

Through the self-checking curve analysis of the daily mean value of drilling strain in Tengchong Station in recent 5 years(January 2017 to March 2022),it is considered that the observation data are sta-ble and reliable.The data interference sources are summarized,and the main interference factors affecting the change of borehole strain data are water storage interference,rainfall interference,air pressure muta-tion interference and heavy machinery construction interference.The coseismic response analysis of borehole strain data in Tengchong Station shows that the coseismic response of the data is good and corresponds well with seismic waveform records.
