二等水准区段不符值正值累积问题的研究

Research on Continuous Accumulation of Non-conforming Positive Values in Summer Second Leveling Segment

二等水准仍是目前建设省级高程控制网中应用最广泛、最可靠的技术手段,在青海省二等水准网测量工作中,观测正值夏季,受尺承下沉影响,测段不符值产生了持续的正值累计,为解决此问题,我们尝试了多种方法,最终解决了此问题。

Secondary leveling is still the most widely used and reliable technical means in the construction of provincial elevation control network.In the survey work of Qinghai Province’s second-class leveling network,the observation is in the summer,and due to the influence of footage subsidence,the non-conformity of measurement section produces a continuous positive accumulation.To solve this problem,we have tried many methods,and finally solved this problem.
