Numerical Analysis of Horizontal Impact Resistance of Rock Socketed Pile with Steel Casing

Based on a Wharf project in Chongqing, this paper carries out experimental research and nonlinear finite element analysis the impact resistance of steel casing rock socketed pile inland river frame under horizontal load. The results show that force its growth rate, bending moment concrete core, maximum lateral displacement top increase significantly with energy, linear is better. Under same mass, decreases, core vibration center value (platform value) increase, increase. mass m threshold, criterion different dynamic response forms body proposed. threshold corresponds to development plastic hinge at root body. Through parametric method, it obtained velocity, meet parabolic spherical relationship.
