某大坝沥青混凝土心墙变形监测分析与探讨

以工程实际监测资料分析为基础，经分析确定正位错大小与大坝心墙压应力无必然关系；因而提出：应提高过渡料填筑压实标准以减少心墙竖向变形，岸坡处理应尤为如此；并建议应采用更先进的光纤维传感技术加密对心墙的变形及变形量进行三维空间定位监测。

Analysis and discussion on deformation monitoring of asphalt concrete core of a dam

Based on the measured monitoring data from an actual project,it is determined from the analysis concerned that no an inevitable relationship is there between the size of the positive dislocation and the compressive stress of the core of the dam;and then,it is put forward that the compaction standard for the transition-material filling must be raised,so as to reduce the vertical deformation of the core,especially for the treatment of the bank slope.Moreover,it is suggested that the more advance optical fiber sensing technology shall be adopted to densify the 3-D spatial location monitoring on both the deformation and its amount of the core.
