Method for observing settlement of high-rise building

Abstract

The invention relates to a method for observing settlement of a high-rise building, and relates to the field of building detection. The method comprises the following steps: burying an elevation reference point, a common reference point, an observation working point and a settlement observation point; installing a satellite positioning device and a high-definition camera; performing settlement observation on a building; and calculating the settlement amount, and drawing a settlement curve of each settlement reference point and each observation working point. Therefore, the influence of construction site excavation, bottom surface settlement and ground vibration is effectively eliminated, the elevation datum points can be subjected to joint measurement and mutual inspection so as to be conveniently stored permanently, then people are helped effectively control the whole construction site, and thus the settlement observation result is more accurate.

Description

technical field [0001] The invention relates to the field of building detection, in particular to a settlement observation method for tall buildings. Background technique [0002] In order to timely, accurately and quickly grasp the settlement information of the building foundation changing with time under different loads and ensure the overall quality of the building is stable, it is necessary to observe the settlement of the building. [0003] At present, for high-rise buildings (buildings with a height of more than 70m), if the foundation has a slight uneven settlement, it will cause a large horizontal deviation of the above-mentioned high-rise buildings. Affected by loads such as wind force and building self-weight, the high-rise buildings that could not maintain the flatness in the horizontal direction will be more inclined, thus bringing greater safety hazards to the high-rise buildings. Therefore, in view of the strong sensitivity of high-rise buildings to the uneven...

Problems solved by technology

[0005] The settlement observation method described in the above comparative document 1 has the following defects: comparative document 1 does not record how to arrange the settlement reference point, observation work point and settlement observation point during building settlement observation. At the same time, the settlement reference point, observation work point and There is no record in the above-mentioned prior art scheme about the specific number and specific arrangement locations of the settlement observation points. Therefore, people still cannot know how to observe the settlement of the building after seeing the comparative document 1.

[0007] The settlement observation method described in the above-mentioned comparative document 2 has the following defects: 1. During actual construction, the stability of the settlement reference point
