摘　　要：结合生产科研项目的实施,阐述了沉降观测作业仪器的选择与检验、沉降点与基点保护等问题。分析了视准轴误差、水准尺立尺误差等对观测成果的影响及规律,提出了消除或减弱仪器误差、外界条件影响及观测误差的基本方法,从而有效提高了外业沉降观测精度。Combined with the implement of production research projects, rome problems such as selection and check of operation instrument of settlement observation, settlement points and protection of basic points were elaborated. Collimation errors, stuff setting errors, and its influences and rules on the settlement result were analyzed. Some basic methods such as weakening or eliminating instrumental errors, field condition errors and observation errors were proposed, which will effectively improve the observation precision of field settlement.
