摘要
在地铁施工建设过程中,测量工作对于盾构掘进、结构施工的准确性有着重要作用.在地铁施工控制测量工作中,需要将地面上的控制点通过联系测量的形式,将坐标、高程传递到地下控制点,以地下控制点作为基线点来指导施工.地面控制点的成果作为联系测量起算依据,其精度直接决定了地下控制点的精度.文章通过分析地面控制网变形对盾构基线边的影响,探讨了提高控制测量精度的相关措施,如优化地面控制网、应用高精度的仪器设备等.
Abstract
In the process of subway construction,the measurement work is very important,which plays an important role in the accuracy of shield tunneling and structural construction.In the subway construction control measurement work,it is necessary to transfer the coordinates and elevation of the ground control points to the underground control points through connection survey,and use the underground control points as the baseline points to guide construction.The results of ground control points are used as the basis for connection survey,and their accuracy directly determines the accuracy of underground control points.By analyzing the influence of ground control network deformation on the baseline edge of the shield,this paper discusses relevant measures to improve the control measurement accuracy,such as optimizing the ground control network and applying high-precision instruments and equipment.
