- Abstract
Influenced by the dead loads and the cyclic loads of upper structure of bridge over a long period of time, it will have important significance to study the settlement, bearing capacity and skin friction, relations between cyclic loading and the nature of the soil for reconstruction in service period of bridge piles. The fiber gratings(strings) were sticked on the surface of steel pile to form the model pile. Based on the model test, the bearing behavior of pile foundation under vertical cyclic loading is studied systematically. Analyzing the values of settlement of pile top, axial force of pile, side friction of pile and soil stress around the pile embedded in the soil, which revealed the relationship between the test loading times and the characteristics of pile bearing. Fitting the curves of the relationship between the bearing capacity of pile and settlement of pile top with static loading model test in loess soil. And fitting the curves of the relationship between the settlements of pile top and cyclic loads times under the cyclic loading model test in loess soil. And it will provide the supporting method for the practical engineering demand.
