Research status and future development prospect of suspension bridge anchorage

With the increase of the span of long-span suspension bridges, higher requirements are put forward for anchorage foundation. The larger and larger size of anchorage leads to higher and higher cost. The information of the existing gravity anchorage foundation of suspension bridge is statistically analyzed. The traditional anchorage foundation and the new pile anchorage composite structure foundation are analyzed from the angle of the standard method and the mechanism-based analysis method. The relevant method and strategy of stability and deformation analysis are put forward, and some suggestions for the researches on the new pile anchorage composite structure foundation are given.
