Deformation monitoring refers to the measurement work to understand and analyze the deformation law of buildings or structures during construction and use, so as to obtain the deformation amount or deformation rate and deformation law of the monitored object. When conducting deformation monitoring, deformation monitoring points need to be set, and multiple factors such as the characteristics of the building, engineering geological conditions, and monitoring purposes and requirements should be considered. Among them, what aspects need to be considered in the layout of deformation monitoring points?
1. Taking into account the characteristics of the building: When arranging deformation monitoring points, it is necessary to comprehensively analyze factors such as the height, shape, load size, and usage of the building in order to select an appropriate monitoring method.
2. Select the appropriate monitoring method: According to the engineering geological conditions and construction conditions, an appropriate monitoring method should be selected to achieve the purpose of monitoring.
3. Conduct continuous monitoring: deformation monitoring must be carried out continuously, at least once a quarter, to obtain more accurate deformation data.
4. The location of the deformation monitoring points: In order to obtain the deformation law of the building or structure, it is necessary to arrange the deformation monitoring points around it. Generally, it should be arranged in a suitable position around the building or at the far end.
5. Embedding depth of the observation point: the embedding depth of the observation point is generally 0.5~1.0m, so as to observe the deformation from the foundation of the monitoring point.
6. Determine the observation cycle: The observation cycle should be determined by considering factors such as the characteristics of the building, the surrounding environment, and the construction progress, so as to ensure the accuracy of the monitoring data.
The above are the layout principles of deformation monitoring points, which should be selected and arranged according to the actual situation to ensure the smooth progress of deformation monitoring work.
