Abstract
This paper first analyzes the tilting reasons of a brick-concrete building in Yunnan province in China. Then, a comprehensive rectification method which combines the stress release method and the excavation of stress release trench was put forward. This method uses the anchor static pile in order to guarantee the safety of the building in the process of rectifying. The practice case showed that the inclination rate of the building returned to 3 % from 14.4 %, which proved the efficiency of the proposed method.
Highlights
There are different reasons of buildings to tilt due to the soil properties of the buildings in different areas which always have the great characteristics of the regional differences
This paper puts forward a systematic research on tilt building, including the reasons, the rectification and the reinforcement methods, which combined with an example of brick-concrete building in soft-clay area of Yunnan Province
Through the actual research and geological prospecting situation, we found that the main reason for the uneven settlement of our case is in three areas, loads from the superstructure, foundation and infrastructure programs, as well as the surrounding environment
Summary
There are different reasons of buildings to tilt due to the soil properties of the buildings in different areas which always have the great characteristics of the regional differences. The movement of water often causes the uneven settlement of building foundation in collapsible loess area [1]. This paper puts forward a systematic research on tilt building, including the reasons, the rectification and the reinforcement methods, which combined with an example of brick-concrete building in soft-clay area of Yunnan Province. It has a great value for similar rectification projects
