| Abstract: | 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. |
