Analysis on Reliability and Coseismic Response Characteristics of YRY-4 Component Drilling Strain Data at Tengchong Station
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.
