Settlement mark placement location requirements and monitoring general requirements
The placement of the settlement mark is one of the key factors to ensure the accuracy and reliability of the monitoring data. Here are some specific requirements for the location of the settlement mark:
1.Choose the right monitoring point.
Before laying the settlement standard, a representative area should be selected as the monitoring point according to the engineering geological survey report and design drawings, combined with the actual situation of the site. The selection of monitoring points should be able to reflect the distribution of soil layers, geological structure, groundwater level, etc. throughout the project.
2.Consider the impact of your surroundings.
When laying the settlement mark, the influence of the surrounding environment on the monitoring point should be considered. For example, the presence of surrounding buildings can create additional stresses on the soil layer, leading to biased monitoring data. Therefore, when selecting monitoring points, these effects should be avoided as much as possible, or corresponding measures should be taken to reduce the error when laying settlement standards.
3.Consider the impact of construction.
During the construction process, there may be disturbances to the soil layer, which will affect the accuracy of the monitoring data. Therefore, when laying the settlement mark, the monitoring point should be set up in the area with less construction impact as much as possible. If the impact of construction cannot be avoided, monitoring should be strengthened during construction so that errors can be detected and corrected in time.
4.Consider the installation and maintenance of monitoring equipment.
When laying the settlement mark, the installation and maintenance of the monitoring equipment should also be considered. The installation of monitoring equipment should be stable and reliable, easy to maintain and maintain. In addition, sufficient space should be reserved for the installation and maintenance of the equipment for routine monitoring and calibration work when laying the settlement markers.
In addition to the requirements for the placement of the settlement mark, there are some general requirements for monitoring that need to be followed:
1.Regular monitoring.
In order to ensure the accuracy and reliability of the data, the monitoring of the settlement target should be carried out on a regular basis. According to the actual situation of the project and the design requirements, formulate a reasonable monitoring plan, collect data regularly and analyze it. For important areas or key parts, the frequency of monitoring should be increased so that potential problems can be detected and solved in a timely manner.
2.Data logging and collation.
During the monitoring process, the data of each monitoring point should be recorded and sorted out in detail. The recording of the data should be accurate, complete, and clear for subsequent data analysis and processing. In addition, the data should be filtered and processed as necessary to eliminate outliers and errors and ensure the accuracy and reliability of the data.
3.Data analysis and processing.
The collected sedimentation label data should be analyzed and processed in detail. By comparing the data at different time points, we can find the trend and law of soil subsidence. For abnormal data or data with large errors, necessary corrections or exclusions should be made to ensure the accuracy and reliability of the data. At the same time, it is also necessary to make necessary corrections or adjustments to the data according to the actual situation to reflect the changes in the actual situation.
4.Feedback and application of monitoring results.
The monitoring results of the settlement target have important guiding significance for the safety and stability of the project. Therefore, the monitoring results should be fed back to the relevant departments or units in a timely manner so that necessary measures and decisions can be made. At the same time, it is also necessary to apply the monitoring results to engineering practice, guide construction and operation management, and improve the quality and safety of the project.
