【 摘 要 】

The trials of the automated stress measurement equipment have revealed the necessity to upgrade its component represented by the borehole strainmeter. Application of the digital microprocessing methods for signal measurement and conversion has allowed elimination of negative impacts and enhanced efficiency and reliability of stress-strain control in rocks.
