The purpose of subgrade settlement observation is to monitor the road conditions during construction in real time and to detect possible settlement in the future. Through the observation of subgrade settlement, the following two purposes can be achieved:
1.Control construction risks: In the process of road construction, due to the influence of earthwork excavation, filling and other operations, the roadbed may appear to settle. If the settlement is too large, it will not only affect the quality and safety of the road, but also may cause construction accidents. Therefore, through the observation of subgrade settlement, the abnormal settlement can be found in time, and corresponding measures can be taken to adjust and repair, effectively control the construction risk, and ensure the safety and quality of construction.
2.Improve project quality: Subgrade settlement observation can provide accurate subgrade settlement data, helping engineers and construction personnel understand the subgrade settlement of the road at different stages of construction. These data can be used to analyze the stability and reliability of the roadbed, so as to optimize the construction plan and process, and improve the overall quality of the road project. At the same time, the subgrade settlement observation can also provide an important reference for engineering acceptance and follow-up maintenance.
In order to achieve the above purposes, the observation of subgrade settlement needs to adopt high-precision measuring instruments and professional measurement methods. In the process of observation, it is necessary to record the data of subgrade settlement on a regular basis, and organize and analyze the data. If an abnormal situation is found, it is necessary to take measures to deal with it in time to ensure the smooth progress of road construction and the high-quality completion of road works. At the same time, attention needs to be paid to protecting the accuracy of the measuring instrument and the reliability of the measurement method to ensure the accuracy and reliability of the observation data.
