Cable-stayed bridge cable bent tower anchoring area prestressed reinforcement impact protection test device and method
The invention discloses a cable-stayed bridge cable bent tower anchoring area prestressed reinforcement impact protection test device and method, and belongs to the technical field of cable-stayed bridge impact protection tests. The cable-stayed bridge cable bent tower anchoring area prestressed reinforcement impact protection test device comprises a loading device, a concrete model, tensioning mechanisms, a tensioning pedestal, a high-speed camera and an acquisition instrument; the tensioning pedestal is distributed on the side wall of a concrete model in a semi encircling form; the pluralityof tensioning mechanisms and the loading device are installed on the tensioning pedestal; extension lines of the multiple tensioning mechanisms are distributed vertically and horizontally and connected with the concrete model; the high-speed camera is arranged obliquely above the concrete model; and the high-speed camera, the tensioning mechanisms and the loading device are all electrically connected with the acquisition instrument. From the five aspects of protection effect, durability, construction difficulty, economic cost and structural appearance change degree, schemes of protection types are comprehensively compared with each other and selected, protection type selection of prestressed tendons is realized, and bridge engineering design accuracy and construction safety are ensured.
本发明公开了一种斜拉桥索塔锚固区预应力钢筋冲击防护试验装置及方法，属于斜拉桥冲击防护试验技术领域，包括加载装置、混凝土模型、张拉机构、张拉台座、高速摄像机和采集仪，所述张拉台座以半包围形式分布于混凝土模型侧壁上，且张拉台座上安装有多个张拉机构和加载装置，多个所述张拉机构的延长线呈纵横分布并与混凝土模型相连接，所述混凝土模型的斜上方设置有高速摄像机，所述高速摄像机、张拉机构和加载装置均电性连接有采集仪。从防护效果、耐久性、施工难度、经济成本和构造外观改变程度等五个方面，对防护类型的方案进行综合比选，得出预应力筋的防护选型，确保桥梁工程设计精准和施工安全。
