Abstract

Abstract

In actual projects, there are many factors which may influence the ultimate bearing capacity of ground anchors.Some problems like defects in calculation method and constuction process would result in discrepancy between theorical an chorage force and actual force.Some investigation tests of pre-stressed cables were done to obtain the relationships between the axial force and the axial displacement of the prestressed cables;and to acquire how the fixed length affects the bond stress.It was also proposed some problems that easily happened in actual projects.
- destructive tension test,
- fixed length,
- bond stress,
- efficient factors
