摘要
针对几何水准测量方法在沉降监测中存在的问题,提出挂尺观测的监测方法。介绍挂尺观测的原理与注意事项,结合大量实验及工程应用验证了新方法的可行性。分析应用结果表明,挂尺观测有利于提高观测精度和工作效率,监测标志更易保护,保证了监测数据的连续性。
A new method of leveling with hanging level rod is presented in this paper based on the deficiency of traditional spirit leveling in subsidence monitoring. First, the principle of hanging level rod observation is introduced, next, points for attention are summarized. Finally, the feasibility of the new method is verified by experiments and construction projects in practice. The results demonstrate that the precision and work efficiency can be improved with the new method, which makes the monitoring marks more easily protected, and the continuity of monitoring data is well maintained.
