Description :

　　The commonly used method is to follow the second-order leveling measurement settlement deformation observation regulations to meet the high-precision measurement requirements for bridge settlement deformation. According to the high-precision measurement requirements for settlement deformation, the general settlement deformation monitoring network uses a graded network to observe and control the layout step by step. It is mainly arranged in three categories: corresponding benchmark points, settlement deformation points, and working base points.

　　The reference point is the basic component level in settlement observation and measurement, which has a direct impact on the observation degree of settlement. The setting of the reference point is generally based on the corresponding second-class measurement level. The location of the reference point and the area of settlement deformation need to maintain a certain safe distance. At the same time, the reference point also has requirements for network construction, requiring the establishment of independent monitoring networks, not less than 3; Observation points are an important part of the work of design units, and it is necessary for them to do a good job in designing the location, shape, and material of the observation points, which is conducive to their convenient use in the later stage, and strict installation of the observation points is also required.

　　Installation personnel must strictly follow the relevant requirements during the installation of observation points. In the use of observation points, daily maintenance work needs to be done well. If any damage is found in the observation points, it should be reported and repaired in a timely manner.

　　The work base point and observation point are closely related, mainly to determine the starting and ending positions of the corresponding observation points, which need to be measured according to the national second-class level. The distance between points is generally required to be within 200m. Due to the close relationship between observation points and many aspects, it also has a great impact on the observation process. Therefore, observation points need to have good stability and be able to be stored for a long time, which can effectively promote uninterrupted observation work.

　　In addition, in addition to observing according to the prescribed accuracy, it is also necessary to measure according to the national second-class standard during observation. There are strict requirements for the length and height of the line of sight, the difference in line of sight before and after, and the difference between two readings. Generally, the length of the line of sight should not exceed 50m, and the difference between two readings should not exceed 0.4mm.

　　Observation instruments are the fundamental tools for measuring data, and effective maintenance is necessary to ensure their normal use. When conducting observations, it is necessary to avoid direct sunlight on the instrument and ensure that its temperature is suitable. Do not immediately read the measurement results after imaging. Wait until the image is stable and clear before reading. In order to avoid unstable conditions during instrument observation, it is also necessary to eliminate the possibility of vibration and shaking.

　　In addition, observers should cooperate with the observation, have a rigorous observation attitude and awareness, gradually verify and validate the observed data, and effectively record and analyze any abnormal information data.

　　On February 7th, standing in front of one of the iconic venues in Beijing - the China National Ski Jumping Center known as "Snow Ruyi", gazing at the towering mountains hidden by white snow, Kang Jinzi's sense of pride surged. She said, "The grand opening of Beijing showcases China's comprehensive national strength to the world. I am proud of the prosperity and strength of my motherland

　　As a Qinghai athlete, Kang Jinzi also feels a great responsibility on his shoulders. As a retired athlete, she is also proud to participate in Beijing and fulfill her dream of the Olympics in a different capacity.

　　This pride stems from passion and benefits from Qinghai Province's vigorous development of winter sports and active formation of winter sports teams. In 2008, Kang Jinzi became a racewalking athlete in the Qinghai Provincial Sports Engineering First Brigade and retired at the end of 2017. After retiring, she participated in skiing training organized by the General Administration of Sport of China for retired athletes and obtained the level of skiing referee. At the end of 2018, the Qinghai Provincial Sports Bureau established the Qinghai Provincial Cross Country Skiing Team, and she was appointed as the coach.
