摘要
结合"城市轨道交通工程测量规范"中的相关技术要求,从理论上分析盾构隧道横向贯通误差的主要来源及各阶段平面控制测量误差限值的合理分配,并针对盾构法施工地铁隧道的特点,探讨长大盾构区间地面平面控制点的布设原则及限值的优化配赋。
Based on the relevant technical requirements of Urban Rail Traffic Engineering Measurement Specifications, the text analyzed the main source of horizontal through error and the reasonable distribu- tion of plane control measurement error-limit with each phase theoretically. And in the light of the charac- teristics of subway tunnel construction by shielding method,discusses the layout principle of plane control points and the optimization match o{ limits about long shield interval.
