从地震监测中精密水准测量的实际工作出发,对每测段、区段、路线所测高差进行高差改正,对所形成的独立环进行环闭合差计算,判断其是否超限,若满足环闭合差限差,则观测数据合格,若超出限差,则分析原因、重新测量,最终使独立水准环闭合。 Based on the actual work of precise leveling in seismic monitoring, the height difference correction is performed on the height difference measured in each section, section and route, and the closed loop difference of the formed independent ring is calculated to judge whether it exceeds the limit. If the difference between the closed loop and the closed loop is poor, the observed data will be qualified. If the limit is exceeded, the reason is analyzed and the measurement is re-measured to finally close the independent level loop.
