Abstract

Monitoring on the deformation of the engineering rock mass is one time and cost consuming task，especially for the cases with large monitoring section and long monitoring distance and when the power supply is not properly available. To overcome these difficulties and improve the efficiency of monitoring，we present anon-contact measurement system. The principle of this method is converting the internal displacement of surrounding rock to the rotation angle of the disk. A diaphragm is arranged below the rotating disk with an observation window. The intensity of the light reflected from the different regions of the diaphragm is changed，and the rotary angle of the disk is calculated by the intensity of reflected light. Through the laboratory test，it shows that there is a good linear relationship between the intensity of the reflected light and the rotary angle of the disk. By modeling，the monitoring precision of the internal displacement of surrounding rock can be effectively improved. The new measurement scheme was verified in Long men tunnel. Comparison test and surrounding rock grade survey show that the results of measurement are in line with the actual situation. The new measurement system can achieve non-contact measurement and reach the accuracy of engineering measurement.

Key words： tunnelling engineering automatic measurement surrounding rock internal displacement displacement meter monitoring survey
