Abstract Through theoretical calculation,it is found that within the deep bedrock of one meter deep, daily temperature fluctuations is only one percent of daily temperature fluctuations of air in cave.A meter long unicom tube tiltmeter is coupled with the selfstressing cement in the deep bedrock of one meter in the cave,the stability and high frequency performance of the volume strain meter in tunnel can be improved.
Key words ：
cave volume strain
selfstressing cement
rock groove
stability
high frequency
