国家第三期一等水准测量布设水准点方法的探讨

本文通过对国家一、二等水准测量水准标志保存现状的分析总结,提出了国家第三期一等水准测量设计时要统筹考虑国际空间坐标基准框架建设和重力基准框架建设的点位布设方案,使各基准框架之间均有联系的布网思路;布设水准点和选用标石类型时应有主次之分,并对布设普通水准点时优先选用墙脚水准标志的必要性和可行性进行了分析研究。

Method of benchmark layout based on the national third stage of first order leveling

The mark layout solution,in which the development of international base framework for space coordinate and that of gravity datum were considered together when designing the national third stage of first order leveling was presented in this paper based on the analysis of the preservation status of benchmarks for national first and second order leveling to make all the base frameworks to be connected.The distinction should be made to layout benchmarks and to select appropriate stone marks.The necessity and fe...
