摘　　要：试验以絮凝剂和减水剂为主要原料,通过测定PHC管桩工作性能指标,研究了不同类型和环境温度下絮凝剂对PHC管桩性能的影响。试验数据表明:阴离子型聚丙烯酰胺对混凝土管桩的综合影响最大;且在不同环境温度区间内,絮凝剂对混凝土管桩的影响呈现出先上升后下降的趋势。The experiment used flocculants and water reducing agents as the main raw materials,and by measuring the performance indicators of PHC pipe piles,the influence of flocculants on the performance of PHC pipe piles was studied under different flocculants types and environmental temperatures.The experimental data indicates that anionic polyacrylamide has the greatest comprehensive impact on the concrete pipe piles,and the effect of flocculants on concrete pipe piles shows a trend of first increasing and then decreasing in different environmental temperature ranges.
