Based on the anti-slip and anti-friction test method and test process of the cable saddle of Lassa Najin Bridge, the loading test principle of the epoxy gripping anti-slip anchorage device is proposed. According to the requirements of the anti-slip test plan, the epoxy gripping anti-slip anchorage device is tested, and the static anti-slip mechanical properties of the cable bridge tower anchorage structure of the low tower cable-stayed bridge are checked, and the test results are summarized and analyzed. The anti-slip and anti-friction performance of the saddle of the cable-stayed anchor cable is proposed from the aspects of design and construction.
