Mesoscopic damage model of wharf reinforced concrete pile parameter calibration and model validation
When the pile is used in the wharf,the reduction of the bearing capacity of the pile due to the deterioration of various factors on the material characteristics of the pile has become an important influencing factor for the safe and healthy use of the high-piled wharf.In order to more accurately predict the damage and deformation characteristics of reinforced concrete piles in the complex hydraulic environment(ship load,wave load,etc.)of inland wharves,we design a horizontal loading device that is easy to make and operate to carry out horizontal graded loading tests on reinforced concrete pile,obtain the tensile load-strain curve at the bottom of the pile,and build a three-dimensional particle flow discrete element reinforced concrete pile model by PFC3D software.Then we calibrate micro-parameters of the model,and verify the rationality of mechanical properties of the model by results of physical tests.
