| 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.

| Abstract: | Based on the prototype observation data of Lijiaxia arc da m 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 pressu re factor of this model is calculated and the displacement-mixing monitoring mod el is established.The computing results show that the fit precision of these tw o models is good and it can play an important effect on the dam safety monitorin g. |
