摘要
从地铁控制基标必须满足的精度要求着手,反向估算出贯通后两站一区间联测的地下导线测量应满足的精度指标,进而估算出作为起算点的车站底板控制点应满足的精度要求,为实际工作提供了理论依据,并以青岛地铁3号线某区间控制基标测量为例,验证了地下导线测量精度指标的实用性和合理性。
Beginning with the precise requirement must be satisfied for control disjunction marks,the paper deduces precise parameter satisfied by tunnel traverse surveying after connected with two stations,and further deduces precise parameter satisfied by control points on the ground of the station.The paper offers the theory of the basis for actual work,and advances practicality and rationality or tunnel traverse surveying enormously.
