摘要
针对当前大坝安全监控指标拟定方法未同时考虑运行期的监测成果、结构材料特性以及结构荷载情况的问题,建立基于变形监测数据的近海软基水闸水平位移监控指标拟定方法。以某近海软基拦河闸变形监测资料为基础,通过对长序列的水平位移监测成果进行分析,结合库水位变化情况,研究闸坝变形特征及与库水位的相关性,获得该枢纽的位移变化规律,同时建立水闸三维有限元模型,分析不同工况下的水平位移值,可为该类水闸监测与安全运行提供指导。
A combined method to determine safety monitoring index for concrete dams based on analysis of horizontal displacement monitoring data of offshore soft foundation was proposed in this paper. A case study of deformation monitoring data of a coastal soft foundation was carried out,based on the analysis of the results of horizontal displacement monitoring of long sequence,the deformation characteristics of the dam and the correlation between the deformation characteristics and the water level are analyzed,and the displacement rule of the horizontal displacement is obtained. At the same time,the three-dimensional finite element model of the sluice is established to calculate the horizontal displacement value of the sluice,which can provide guidance for the monitoring and safe operation of the sluice.
