摘要：
The anchorage zone of cable-stayed bridge tower is the key zone related to the safety of the bridge. Traditionally, prestress tendons are arranged in the concrete tower, in order to avoid the shortcoming of circumferential tendons, a new layout of prestress tendons named as "one-way prestress tendons" is put forward. This paper analyze the spatial stress state of this new design by the software ANSYS. Three load cases are considered: tensioning the prestress tendons only, loading the designed stay-cable force and the one stay-cable broken condition. The results show that: this new design can ensure the safety of the tower and will be reliable in practice.
