Relevant regulations for displacement observation of high-rise buildings?

1. Building displacement observation can measure the inclination, horizontal displacement, deflection and lateral displacement of the foundation pit wall of a building separately or in combination as required, and monitor the landslide of the building site.

2. For displacement observation, the design and technical preparation of the observation scheme should be made according to the characteristics of the building and the requirements of measurement, and the cooperation of the entrusting party and relevant personnel should be obtained.

3. Displacement observation signs should be designed according to the characteristics of different buildings. Signs should be firm, applicable and beautiful. If it is limited by conditions or a high-rise building, you can also choose the spire, lightning rod and cylinder (sphere) edge with obvious characteristics on the deformed body as observation points. For temporary structures such as foundation pits or rock and soil bodies, signs should be firm, durable and easy to protect.

4. For displacement observation, line-of-sight method, angle measurement intersection method or direction difference intersection method, polar coordinate method, laser aiming method, throwing point method, small angle measurement method, inclinometer method, vertical line method, laser displacement meter automatic recording method, GPS method, laser scanning method or close-range photogrammetry method can be selected according to field operation conditions and economic factors.

5. The displacement observation of all kinds of buildings shall be submitted in time according to the provisions of Section 9. 1 of this specification.
