With the rapid development of society and the continuous progress of the technological era, urbanization has become an inevitable trend in China. Today, with limited land resources and emphasis on urban landmark buildings, high-rise and even super high-rise buildings are increasingly entering people's sight. As the height of buildings continues to increase, various factors will inevitably cause deformation, and settlement deformation is one of the important ones.

According to Article 3.7.3 of the Technical Specification for Concrete Structures of Tall Buildings, for buildings with a height not exceeding 150m, the ratio of top displacement to floor height varies from 1/550 to 1/1000 depending on the structural system. For buildings with a height of not less than 250m, the limit value shall not exceed 1/500. In other words, the scale is "meters".

Intuitively speaking, CITIC Plaza in Guangzhou is 391 meters high, with a maximum displacement of 0.78 meters at the top. The Jinmao Tower in Shanghai is 403 meters high, with a maximum displacement of 0.8 meters at the top.

Buildings exceeding 300m in height exceed national regulatory limits and require professional review and special design, as each building has a unique design with varying degrees of sway.

The Burj Khalifa, formerly known as the Burj Khalifa or the Burj Khalifa, is the tallest building in the world. The Burj Khalifa is 828 meters high, with a total of 162 floors and a construction cost of $1.5 billion. The skyscraper swings 10 feet (over 3 meters) in the wind.

According to current regulations, settlement observation is required for high-rise buildings, towering structures, important ancient buildings, and continuous production facilities and power equipment foundations. In particular, settlement observation technology should be applied during the construction process of high-rise buildings to strengthen process monitoring, guide reasonable construction procedures, prevent uneven settlement during the construction process, provide timely feedback information, and provide detailed first-hand information for survey, design, and construction to avoid damage to the main structure of the building or quality problems affecting its functional use caused by settlement, resulting in huge economic losses.

Huilian Technology's tilt angle sensor has a wide range of applications in high-rise building settlement. By using precise dual axis tilt angle measurement, it provides accurate data to the detection personnel and provides "escort" for the building.
