Damage Analysis Of Sea-Crossing Bridge Main Pier Pile Foundations Under Wave Loading By Scouring Different Situation

摘要

Since the Bridge is generally span, the main pier and more in the deep water area, combined with the harsh coastal or marine environments, heavy marine traffic must be many ways to strengthen security maintenance Bridge, the current damage identification and safety warning technology by the upper structure more attention to the role of Bridge often bear strong winds, big waves. Since the wind - waves - liquid coupling mutagenic effects, long-term effects, effects of fatigue and the effects of aging and deterioration of materials and other unfavorable factors, in order to grasp the Sea-Crossing Bridge Main Pier Pile Foundations work under wave loading by scouring different situation state and force deformation characteristics, the present analysis Theoretical analysis of wave loads by different scouring status under the numerical simulation method.
