METHOD FOR MEASURING DISPLACEMENT OF BEDROCK

摘要

PROBLEM TO BE SOLVED: To provide a method with which the displacement of bedrock can be measured with high accuracy as much as possible, even though the cast is relatively low. SOLUTION: This method uses an acceleration sensor or speed sensor, which measures the acceleration or speed of vibrations caused by the displacement of the bedrock. The acceleration or speed sensor is fixedly set up in a measuring hole bored into the bedrock. The displacement of the bedrock is obtained by receiving and measuring the vibrations, caused by the displacement of the bedrock by means of the sensor and respectively integrating measured acceleration values twice or speed values once with time.
