DiNi12型数字水准仪在区域水准测量中的应用

摘要

In this paper, the Rydelek-Sacks test method for estimating the minimum magnitude of completeness (Mc) is introduced. Using this test method combining with other methods, on the basis of earthquake catalog of Shandong area since 1970 , the Mc of each earthquake tracing region in Shandong area are determined: Mc of Yishu region is 2. 4; Mc of western region of Shandong is 2. 0; Mc of eastern region of Shandong is 2. 8. Finally, the advantage and problems of the method are also summarized and discussed.%对蔡司和天宝公司生产的DiNi12型补偿式自动安平数字水准仪进行野外试验,天津西部试验里程409.3km,施测131个测段,组成13个闭合环,每个闭合环均采用2台仪器测量数据.试验结果表明,在视距50 m以内情况下,精度仍能达到一等,作业速度可达5.4 km/d.两处跨断层综合观测场地测量,施测里程115.9 km,视距小于30 m,测段35段,作业速度2.8 km/d.试验证明DiNi12型数字水准仪可以代替Ni002和Ni002A型自动安平水准仪用于区域水准测量.
