复杂条件下测站考证方法初探

Research on textual method of station in complex condition

以测站考证相关概念和考证应遵循的基本原则为出发点,揭示了测站考证核心工作内容即为基面改正数的复核或重算。围绕基面改正数计算,分析了基面改正数组成和确定基本水准点冻结高程时可能遇到的四类情形及应对措施。面对复杂条件,通过绝对基面间高程换算和灵活的误差处理等手段探索出了一套较为切合实际、合理可行的测站分类考证方法。

Taking related concept and basic principle of station textual research as a starting point, the core content of the research is revealed, namely check and recalculation of the basal plane correction. Composition of basal plane correction is analyzed. And four situations and countermeasures which may be encountered in determining the freeze elevation of fundamental bench mark are analyzed. By elevation conversion of absolute basal plane and flexible error processing, a reasonable and feasible research method is explored.
