Abstract: Combined with prototype observation data, statistical analysis on the working behavior of Shuibuya concrete face slab rock－fill dam was carried out.The results showed that the settlement and horizontal displacement were in line with the general laws, the filling was of good quality and dam deformation was controlled within a reasonable range.But the uneven settlement of the left slope and main dam meant the possibility of cracks on the face slab which attention should be paid to.

摘要： 利用原型观测资料对水布垭面板堆石坝的工作性态进行统计分析，分析成果表明水布垭面板堆石坝的沉降和水平位移符合一般规律；左岸陡坡坝段与坝主体不均匀沉陷现象明显，面板出现裂缝的可能性较大；坝体填筑施工质量良好，坝体变形控制在合理范围内。
