摘要
为了分析2023年汛后上桥枢纽的安全情况,对汛后枢纽的变形资料进行分析.以船闸为例,通过收集现场各监测点的变形数据,船闸左闸室墙南北方向上的最大位移点为J9,累计向南位移7.95 mm,东西方向上的最大位移点为J10,累计向西位移7.60 mm;右闸室墙南北和东西方向上累计位移量最大点均为J5号点,累计向北位移7.10 mm,向西位移7.10 mm.建议加强观测并在闸区范围外加设水准基点,以提高枢纽监测精确度.
Abstract
In order to analyze the safety situation of the 2023 Shangqiao hub after the flood season,the deformation data of hub after the flood is analyzed.Taking shiplock as an example,by collecting the deformation data of every monitoring point on site,the maximum displacement point of the left lock chamber wall in the north-south direction is J9,and the cumulative displacement in the south direction is 7.95 mm.The maximum displacement point in the east-west direction is J10,and the accumulative displacement to the west is 7.60 mm.The maximum accumulative displacement of the right chamber wall in the north-south and east-west directions is point J-5,with the accumulative displacement to the north and west being 7.10 mm and 7.10 mm respectively.It is suggested that the observation should be strengthened and the base point should be set outside the gate area to improve the monitoring accuracy.
