坝体的施工工序关系到大坝的施工成本和坝体变形状况，通过对面板堆石坝堆石体施工方法的探讨，得出反抬法施工对避免面板堆石坝不协调变形有积极作用。面板堆石坝的结构分区也是影响面板堆石坝工程造价的一个重要考虑因素，结构分区的重点研究是次堆石区的分布范围。结合水布垭面板堆石坝的研究表明次堆石区的材料对面板堆石坝蓄水有比较大的影响。

The results showed the maximum cyclic stress of CFRP bar should be under 70 percent of ultimate tensile stress; when the maximum cyclic stress decrease 5 percent of ultimate tensile stress, the fatigue life of CFRP bars increase generally 10 times; with the decrease of cyclic ratios, the fatigue life of CFRP bars decrease heavily; for the brittleness, CFRP bar should possess a higher reserve of strength, the margin of safety against failure is a necessity; according to experimental cyclic stress-fatigue life curve, the fatigue behavior of CFRP bar is much better than the fatigue behavior of Q235 steel.
