| 摘 要： | 预应力混凝土管桩是近年来出现的一种新桩型。由于该桩型在地基加固、施工工期、工程造价及环保等方面与传统地基处理方法相比具有较大的优越性,因此在工程中得到了广泛应用。但是静压预应力混凝土管桩注浆后的应力应变特性研究很少,理论的滞后制约了该技术的推广。在前人工作的基础上,通过现场足尺试验对静压预应力管桩桩底注浆后桩身承载力特性进行了研究。

| Abstract: | The type of prestressed concrete pipe pile appears in recent years.Compared with traditional foundation treatment,the pipe pile has greater superiority in consolidating of foundation,construction preriod,construction costs and environmental protection,so it is used extensively in projects.There is lack of study in stress-strain property of static-pressure prestressed concrete pipe pile of post grouting,and application of the technology is restrained.Based on the predecessor’s study,bearing capacity property of static-pressure prestressed concrete pipe piles on post grouting is studied by on-site full scale test. |
