摘要
随着城市轨道交通的建设规模不断扩张,复杂的施工工艺、地质情况及周边环境也越发普遍。特别是在地铁隧道施工中,这些不利因素限制了常规的联系测量方法的应用。介绍了一种经过优化改进的激光铅锤仪联合定向方法,并在地铁暗挖竖井施工中得到了应用,并取得了良好的效果,为今后同类工程施工提供可借鉴的经验。
With the continuous expansion of urban rail transit construction scale,the complex construction technology,geological conditions and the surrounding environment are more and more common.These disadvantages limit the application of conventional methods of connection measurement especially in the subway tunnel construction.An optimized and improved combined orientation method of laser plumb instrument is introduced,and has been applied in the construction of underground shaft in subway.The good effects are achieved and the reference can be provided for the construction of the similar projects in the future.
