摘要
通过分析已有监测数据,对比相同观测条件下不同观测时长的数据解算结果,验证了监测时长对监测结果的影响,提出了有利于地面沉降监测的最优观测时长,为制定下一步的监测工作方案提供参考。
Analysis of the previous monitoring data, we contrasted the results of calculation data between different lengths of monitoring time in the same monitoring conditions, and certificated the effects of the monitoring time length to the monitoring results in this paper. At last, we provided effective recommendations for monitoring work plan the next step.
