摘要: 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。

Abstract: Two types of digital levels (Zeiss DiNi12 and Trimble DiNi12) are checked in site and field.The field experiment is carried out in the west of Tianjin.The leveling route reaches 409.3km in length, including 131 segments, which form 13 closed leveling lines.The experiment results indicate that single reading accuracies of first-class can be achieved even when sight distance is below 50m, and the working speed is about 5.4 km per day.For cross-fault deformation observation, the leveling route is 115.9 km in length, which is divided into 131 segments with sight distance below 30 m.The working speed reaches 2.8 km per day.These experiments show that DiNi12 Digital level can applied in region leveling instead of Ni002 and Ni002A automatic levels.-
