摘要
结合李家峡拱坝原型观测资料,对拱冠坝段垂线资料进行了分析,根据数理统计分析方法建立了拱冠坝段2 185 m层测点位移统计监控模型.并结合非线性有限元,对模型中的水压分量进行有限元计算,并与实测值拟合,建立了位移混合监控模型.计算结果表明,两种模型拟合精度较高,可以在大坝安全监测中发挥重要作用.
Based on the prototype observation data of Lijiaxia arc dam and mathematics statistics analytic technique, the data of plumb string of the crown is analyzed and the displacement - monitoring model of the crown segment on 2 185 m layer is set up. Combined with the non - linear FEM, the hydraulic pressure factor of this model is calculated and the displacement - mixing monitoring model is established. The computing results show that the fit precision of these two models is good and it can play an important effect on the dam safety monitoring.
