摘　　要：从闸坝的整体和局部沉降情况,分析潮州供水枢纽闸坝工程的变形状态。从闸坝各闸墩沉降变化过程、不均匀沉降情况和沉降分布特点,分析潮州供水枢纽东、西溪闸坝变形规律,从而把握闸坝工程的变形状态。结果表明闸坝工程经历沉降速率由大变小,沉降收敛渐稳的过程,闸坝呈略向上游倾斜,纵向存在局部不均匀沉降的情况。除个别测点略超设计预计工后沉降外,东西溪闸坝工后整体沉降和不均匀沉降量均在规范和设计要求的范围内,闸坝整体处于基本安全的状态。建议后期有针对性地增设必要的监测设施并加强监测。This paper focuses on the whole and partial settlement to analyze the deformation state of the sluice dam of Chaozhou Water Supply Project.From the process of settlement change,differential settlement and settlement distribution characteristics of each pier of the sluice dam,the deformation laws of east and west river sluice dams in Chaozhou Water Supply Project is analyzed,so as to grasp the deformation state of the sluice dam project.The results show that the settlement rate of the sluice dam project changes from large to small,and the settlement convergence and stability gradually.The sluice dam inclines slightly upstream,and there is local non-uniform settlement in the longitudinal direction.Except for a few measuring points slightly exceeding the predicted post-construction settlement,the overall post-construction settlement and differential settlement of east and west river sluice dam are within the scope of specifications and design requirements,and the sluice dam is in a basically safe state as a whole.It is suggested to set up necessary monitoring facilities and strengthen monitoring.
