Abstract: Mixed- model based on monitoring data and mechanics principles was applied in erection of single point horizontal displacement model and bending line monitoringmodel at Xin'anjiang dam, as well as analysis of damdeformation. Though larger aging displacement, annual displacement increment was minishing. By analysis result, the conclusion was gotten that the dam deformation change was in normal state.

摘要: 采用基于实测资料和力学原理的混合模型建立了新安江大坝水平位移单测点和挠曲线监控模型, 分析了该坝的变形性态。从混合模型的分析结果可以看出, 新安江大坝时效位移虽有增加, 但增加量在逐年减小。因此, 水平位移的变化规律总体上正常。
