摘　　要：介绍了合溪水库粘土心墙砂砾石坝防渗墙变形观测仪器设置,通过对变形观测资料的分析,揭示了大坝施工期防渗墙倾斜位移变形、应力应变、渗流压力的变化规律,为该坝的成功截流提供了有力保障。The instrument arrangement for anti-seepage wall deformation observation in Hexi reservoir clay core and sandy gravel dam is introduced here.Based on the analysis of observation data,the variation regularities of the inclined displacement,stress-strain and seepage pressure during the dam construction period are revealed,which could provide strong guarantee for the successful closure of the dam.
