高速铁路在施工期间,其路基需要进行水平位移监测。由于高速铁路线路周围控制点的稀少与不通视,常规的监测方法受到了制约,在此条件下可考虑使用无定向导线方法进行监测。通过对所采集的数据进行精读评定与分析,并与相应规范中的精度标准对比,判断无定向导线方法能够在精密变形监测中使用。。 High-speed railway during construction, the need for subgrade horizontal displacement monitoring. Due to the sparseness and lack of visibility of control points around high-speed railway lines, conventional monitoring methods are constrained. Under these conditions, the use of non-directional wires can be considered for monitoring. Through the intensive reading evaluation and analysis of the collected data and comparison with the accuracy standards in the corresponding codes, it can be judged that the non-directional wire method can be used in the precision deformation monitoring. .
