一种基于垂直顶升孔的确保特长隧洞贯通的测量技术

A Vertical-jacking Pipe Based Surveying Technique

文章以长达7.2 km的上海青草沙原水过江管工程为依托,详细介绍了一种基于垂直顶升孔的确保特长盾构法隧洞顺利贯通的测量技术,包括隧洞贯通误差预计、平面传递、高程传递、内业计算等。

Taking the 7.2 km long river-crossing raw water supply tunnel as the background,this paper introduces a vertical-jacking pipe based surveying technique which guarantees smooth break-through of the shield tunnel,including the piercing error prediction,plane transfer,height transfer and indoor computation work etc..
