摘要
针对某水电站厂坝连接方式及平缝灌浆高程问题,采用接触问题有限元混合法建立了三维有限元模型,分别计算了10个灌浆高程下坝体、厂坝连接处、厂房的变形及应力变化,据此分析出采用平缝连接、且平缝灌浆到进水管底高程就可确保坝体及厂房的稳定。
For the problem of dam-powerhouse connection type and flat joint grouting elevation of hydropower station, this paper establishes a three-dimensional finite element model by the mixed finite element method of the contact problem and calculates the deformation and stress variation of dam body, dam-powerhouse connection and powerhouse for the ten different joint grouting elevations, respectively. It is analyzed and pointed out that applying the connection of flat joint and grouting to the bottom elevation of inlet tube can guarantee the stability of dam body and powerhouse.
