Problems solved by technology

Both methods are greatly affected by the time environment and distance. Due to the limited data of the results affected by the conditions, it is difficult to normally reflect the settlement and deformation characteristics of the structure, and the efficiency is not high and requires a large number of personnel.
Therefore, it is difficult and inefficient to monitor the settlement of railway piers and abutments in water and sea

Abstract

The invention provides a seaborne settlement observation and measurement method, which mainly comprises the following steps of: arranging settlement deformation measurement points, and establishing a settlement deformation observation reference network; observing a sea pier of the cross-sea bridge; carrying out elevation transmission; carrying out precise triangulation elevation observation; performing second-class level observation; after observation and information recording are carried out, carrying out data processing, carrying out adjustment calculation after closure error, median error and the like meet requirements, carrying out rigorous adjustment on a leveling line, and selecting software which is authenticated to be qualified; and inputting the result data into a database according to a unified format. The method is suitable for long-term observation of the abutment body in water and sea, the stability degree of the structure can be monitored synchronously in the construction process, reliable data basis is provided for the next construction procedure, and the efficiency of railway construction is improved.

Description

technical field [0001] The invention belongs to the technical field of infrastructure construction, and in particular relates to a sea settlement observation and measurement method. Background technique [0002] For the piers in the water and the piers in the sea, one is to assume a steel frame measurement and a pedestrian platform near the pier body, and make a steel frame to support the pedestrian passageway protection around the pier body. First, it will destroy the original water and sea ecological environment. Second, it needs to Long-term use requires anti-corrosion and rust removal measures, plus frequent maintenance, the service life is not too long, and the cost is relatively high; the other is that there are waters where the water level is not very high, consider using ships to reach the pier body when the water level is low Measured nearby. Both methods are greatly affected by the time environment and distance. Due to the limited data of the results affected by t...
