Implement and Control of Monitoring Measurement for Tunnel Construction

YE Qiao (China Railway Group Limited,Beijing 100055,China)  
Research purposes: Monitoring measurement is a complicated and systematical work.This paper describes the whole process of monitoring measurement,including the operation program,operation method and implement requirement,for effectively guaranteeing the implement of monitoring measurement. Research conclusions:The monitoring measurement has the characteristics of the effectiveness for fixed time,continuity and protracted nature.The person in charge of implement of monitoring measurement must well know the key points and management program for implement of monitoring measurement and work out the operational guide book or detailed rules or regulations for monitoring measurement with quantitative indexes as the basis to instruct the monitoring measurement work.During the monitoring measurement,the measured data should be processed and analyzed and data information should be given back in time.The data should be processed and analyzed in accordance with the observation of the surrounding wall and its support for overall identification and dynamic management.The data information should be given back to the construction enterprise in accordance with the grade of shift management for instructing the construction organization and arrangement.Giving monitoring measurement information back is the weak point in implement of fmonitoring measurement,but it is the controlled link.The monitoring measurement is one of important technical measures for prevention of tunnel collapse and control of the deformation of surrounding wall and it is also the important part in management,which should be brought into the management work.
