摘要
基于隔河岩大坝近10年的垂直位移监测数据,通过资料分析和构建统计模型揭示了大坝位移场的时空演变规律。研究表明:观测时序范围内各测点的位移速率逐渐收敛;空间分布上,上游侧呈现左岸大、右岸小的3 mm不均匀沉降,但经渗控措施的合理调控,下游侧表现为拱冠梁最大、沿两岸递减的凸型分布特征,符合拱坝的变形协调规律。
Based on the vertical displacement monitoring data of Geheyan Dam in the past ten years,the spatial-temporal evolution patterns of the dam displacement fields are analyzed through data analysis and statistical model construction.The results show that the displacement rate of each measurement points gradually converges within the observation time range.In terms of spatial distribution,3 mm uneven settlement is observed on the upstream side,with larger magnitudes on the left bank and smaller magnitudes on the right bank.With reasonable seepage control measures,the downstream side exhibits a convex distribution pattern,with the largest displacement at the arch crown beam and decreasing along both banks.The displacements conform to the ordinary deformation pattern of arch dams.
