某矿区高程系统稳定性分析
|
摘要
矿区高程系统由筹建开始,一般经历数十年的建设、改建。在此期间,起算基准不一、高程系统不一致、施测单位不同、日积月累的矿区沉降等问题严重影响着矿区高程系统的精度和可靠性。针对此类问题,文中对某矿区高程系统进行了稳定性分析,重点解决了高程基准点稳定性、高程系统与临区一致性、水准点沉降状况等问题。结果显示,该矿区高程基准点大部分比较稳定,高程系统与临区一致,基岩水准点仅存在小幅度沉降,三等水准基点普遍产生了沉降,但基岩水准点之间高差都符合限差的要求,可以继续使用。
The mining area elevation system started with the preparation of construction, and generally went through several decades of construction and reconstruction. During this period, the precision and the reliability of mining area elevation system was seriously affected by the problems of different starting datum, different elevation system, different surveying units and accumulated mining area settlement. Aiming at this kind of problem, in this paper, the stability of elevation system was analyzed in a mining area, and the stability of the elevation reference point, the consistency of the elevation system and the area, and the settlement of the level point were solved. The results showed that most of the elevation datum points in the mining area were relatively stable, and the elevation system was consistent with the adjacent area. There was only a small subsidence at the bedrock leveling point. Subsidence generally produced in the third-class leveling datum points, but the elevation difference between the bedrock leveling points meet the requirements of the limit difference and could be continued to use.
