Abstract
In some building construction, due to the influence of many factors such as site environment, geological conditions, construction design plan. the construction site environment is complicated and the construction process is staggered. For deformation monitoring under such conditions, a single, conventional monitoring method (baseline method, direction intersection method, corner measurement, etc.) may be difficult to carry out. If according to the characteristics of the project, several monitoring methods are used for comprehensive monitoring. It can better solve the difficult problem of on-site monitoring, and can significantly improve operation efficiency. This paper takes construction monitoring as an example to discuss the research of building displacement observation method under special environment.
Highlights
With the rapid development of my country's economy and the rapid development of modernization, more and more high-rise buildings are being built in large and mediumsized cities. Since these buildings need to be excavated with a deeper foundation during construction, a large foundation pit or high-cut slope will be formed after the foundation excavation, which will make it adjacent to the foundation of the building, especially the high-rise building Deformation will affect its normal use
Deformation monitoring of buildings and their foundations has a complete set of theoretical methods, and has accumulated rich experience, But there are blood lessons[4,5]
If the traditional measurement method is used for daily deformation observation, it will bring great difficulties to the implementation of deformation monitoring, or even work
Summary
With the rapid development of my country's economy and the rapid development of modernization, more and more high-rise buildings are being built in large and mediumsized cities Since these buildings need to be excavated with a deeper foundation (about 30 m) during construction, a large foundation pit or high-cut slope will be formed after the foundation excavation, which will make it adjacent to the foundation of the building, especially the high-rise building Deformation will affect its normal use. Deformation monitoring of buildings and their foundations has a complete set of theoretical methods, and has accumulated rich experience (for example, in June 1985, the accurate prediction and forecast of the Three Gorges landslide of the Yangtze River saved more than 10,000 lives), But there are blood lessons[4,5] These have made mankind more clearly realize the importance of deformation monitoring of high-rise buildings and their foundations. In the basic horizontal movement monitoring of the teaching building of Chongqing No 25 Middle School, we used the total station to measure the distance, carry out the distance difference correction, and find the horizontal movement value of the high-rise building foundation in important directions, which solved this problem[9-11]
