Research on Secondary Attitude Matching of Shield Machine After Starting
In shield tunnel construction,the forming quality of segment directly affects the safety,stability and service life of tunnel.The secondary attitude matching of shield machine is to compare the real-time monitoring and recording data of the shield machine guidance system with the attitude measurement data of the shaped segment,and to calculate the difference between the actual and the preset attitude of the shield machine,the attitude of shield machine is revised again to make the attitude of shield machine return to the preset ideal state.In order to determine whether secondary attitude matching is necessary,a series of construction quality control measures should be taken to eliminate interference.Taking the subway construction project between Fenglehe Road Station and Shushan South Station of Hefei Rail Transit Line 6 as an example,this paper selects representative paragraphs for application research and subsequently verifies the actual effect of the match through the data statistics.The results show that the secondary attitude matching after the start of shield machine can reduce the number of segment damage,which is of great significance for reducing construction costs.
