-
摘要: 随着预应力混凝土管桩应用范围的日益扩大,其耐久性问题显得越来越突出,现有的研究过多集中在单一 影响因素 ,且缺少 系统的研究 。文中提出了 工程 中预应力混凝土管桩的耐久性问题及处理措施,分析了影响耐久性的因素,探讨了多因素综合作用下的耐久性 研究方法 ,为进一步研究解决耐久性问题奠定了基础。Abstract: With the wider application of prestressed concrete pipe piles, the durability problems have become more and more serious. While the present researches pay more attention to single influence factor , lacking of system researches. The durability problems and solutions of prestressed concrete pipe piles in engineering are put forward, the influence factors are analyzed and the research methods under several factors are discussed, these lay foundations for further durability researches.
