闸墩水平位移监测基准选择分析

Analysis on selection of monitoring datum for horizontal displacement of pier

介绍了几种水平位移监测的方法,并针对每种方法给出了适应工况。然后,结合实际监测数据,分析了在采用多测回测角方法进行监测时基准选择的重要性,进而提出在要求同时监测纵向、横向位移,而基准点比较远时或不够稳定时,则可以在相对基准下采用多测回测角的方法进行监测。

Several methods of horizontal displacement monitoring are introduced,and the adaptive working conditions are given for each method.Then,based on the actual monitoring data,the importance of the benchmark selection is analyzed.Furthermore,it can be used to monitor the method of multi-measure angle measurement under the relative datum when it is required to monitor the longitudinal and lateral displacement at the same time,while the reference point is far or not stable.
